What is up with Denise Wisestorm?

First off, I don't want to offend or hurt anyone with this post, I am just genuinely curious about what is going on.

Long story short, I saw a post someone else made a few hours ago, where they asked for SSO YouTuber recommendations, excluding Denise Wisestorm from the possible options. It was not a big deal at first, but as I read through the comments I came across some information I did not know which then lead to me doing some digging; and apparently Denise Wisestorm is homophobic (correct me if I'm wrong, that's just what I got out of research).

A lot of people also mentioned him being problematic and extremely negative (to the point it gets depressive), where I must say I honestly agree with the latter. But that is more of a personal opinion, and it differs per person, other people might find that entertaining or necessary while others might choose to avoid that sort of content.

So, I guess my main question is: what has Denise Wisestorm done to make people dislike or even loathe him (that is NOT how negative he is in his videos)? This comes as somewhat of a shock to me which is why I'm writing this, as I as of now believed he was a community favorite.
