No inappropriate moderation activity was conducted on you.
I'm sorry that your first experience on the site was confusing. You seem to have run up against several different issues, which have convinced you you're being "picked on by a mod" while in reality it's just a variety of community members and several mods working to curate questions, answers, and comments as usual. Let me explain to you what has transpired from the point of view of an experienced site member.
The Timeline
You had a couple initial questions go by fine.
Then you asked Can a creature use its "free" interaction with an object during a bonus action?.
You clearly had some investment in how the answer to this turned out. LegendaryDude answered it, you disagreed, and this led to a lengthy comment thread turned argument that drew flags. There were several flags from site users about wanting to edit in the example to the question but reluctance due to you showing hostility about doing so. You took exception to LegendaryDude's comments and sent us flags about them being hostile, both before and after he really tried to build bridges with you, e.g. " @TrollBourne Neither did I say your question is dumb nor imply it. I am genuinely trying to help you, and genuinely am not sure where the miscommunication has occurred. I sincerely hope you re-read what I have written in that light."
I then moved the comment thread on LD's answer to chat, as it was turning into lengthy back and forth which is not what comments are for on this site; see Why are site comments being deleted?.
You threw more flags about the comment deletion, and SSD provided a link to Meta you had trouble using. You self-posted an answer which wasn't well received and got downvoted. This led to another comment argument on that answer, which SSD deleted, as we do.
So far we're at 35 deleted comments and 8 flags on one question. This is unusual and draws additional attention from site power users and moderators.
Meanwhile you had answers on a couple other questions downvoted - Can the Portent ability of a Diviner Wizard negate a critical hit?, another I'm having trouble finding - and started posting complaining comments about the downvotes. You also started sending mod flags for a variety of reasons, including trying to PM us I guess and also complaining about other questions on the site that are perfectly on topic.
Then you asked your second question, which I have to admit I didn't find extremely coherent in its initial formulation either.
https://rpg.stackexchange.com/questions/92644/is-a-bonus-action-an-action
People tried to help via comments and suggested edits and the question was placed on hold, which is routine for questions that need some workshopping before people try to answer them. But then comments and edits escalated to arguments and flagging. That question is now up to 6 flags and 30 or so comments. Again, a big warning flag to site regulars.
Now we're at the point where you are refusing to take any guidance on how we like to conduct our Q&A here.
"Ladifas, Hey I Can Chan, Nitsua60, and friends...As I appreciate your input to instruct me in the ways of formulating a question, I am a college graduate and think I can word a question in exactly the manner that I would want it to be portrayed. "
"SevenSidedDie...I've got some major problems with you my friend and the next few comments are for you."
And so you've decided you're being "singled out." Your further commenting has come very close to our site "Be Nice" behavior guideline and from my viewpoint seems to be more like escalating and lashing out than "appreciating input."
So what to do?
First, take a moment to calm down. No one's out to get you. In fact, ironically, much of this is being caused by people trying to help you. They may not be trying to help you in the exact way you want, but that's frequently the price of getting help from others.
While you're welcome to write whatever question you want, it'll get closed if site members don't think it's a good question. Answers people don't agree with will get downvoted. Downvotes don't have to be explained. And too chatty comments or comment arguing will be deleted/put to chat, per that other linked meta post. That's just the way the site works. People suggest edits that you are free to accept or revert, but they're just trying to help you get your question reopened as clear and answerable within our site guidelines.
Something like a half dozen site users have tried to help you by trying to explain how to get your questions on track and why your answers got downvoted - commenting, editing, answering, etc. You've interpreted this as being dogpiled on while they intend it as help. You've also misinterpreted the collective editing, closing, flagging, and deleting action of SSD, me, and other site users as being "SSD singling you out." It's not. At most, it's site moderators reacting to an extremely unusual amount of flags and arguments, which is well within your power to quell.
If you don't understand why something is happening or why the site works a certain way, feel free to ask. We understand that this site is a lot more focused than reddit or forums or whatever and that can mean some behaviors seem unexpected here.
But getting wound up about it to the point of being disruptive and hostile isn't a good answer.
