Also, how do you delete your StackExchange account?
Welcome back to Politics.SE. I presume you're referring in your question to my final deletion vote on your answer here a couple of months ago. Firstly, note that this took place before I was elected as a community moderator, so I was only acting then in my role as a high-reputation user.
Nevertheless, if your answer was posted again today in its current form, I would still be in favour of taking similar action. While I appreciate that this is clearly an emotive issue for you, your answer cast aspersions about the motives of the user who asked the question, referred to the question as "nutty", and was needlessly provocative, referring to a public figure throughout as "Orange Man". That is not the level of discourse which is acceptable on this site.
Even after these references were edited out by regular users as well as a moderator, your answer was still, in my opinion, needlessly aggressive, and still referred to a public figure as a "zombie candidate, who actually hates this country", leading me to cast a deletion vote along with two other community members.
I'm afraid I take issue with the assertion you've made about my beliefs in your question title; I don't feel like my actions here warrant such a claim.
To address the question you've posed, Stack Exchange has trusted the community to elect its own moderators, and voters in said election had access to my history of content moderation, as well as the opportunity to pose questions to moderator candidates. Most of my actions as a moderator are available for the community at large to review, and those that aren't can be scrutinised by my fellow moderators as well as Stack Exchange employees.
I'm sorry that you feel like this unfortunate incident has led to you feeling unable to continue to contribute to our site. As Joe W mentioned, information on account deletion can be found here.
