I have noticed that some posts lately have been rather bigoted--especially since the last U.S. election cycle. In my seven years here, I've seen a lot of toxicity--which I expected on an open, diverse forum--but never to the extent of the 2016-2018 period, mainly because of the extremely charged political climate.
Let me put it this way, though: just like there are hateful, ignorant posts, there are others that are reasonable and well-informed. I can say with certainty that if it hadn't been for the latter type, I might still be a homophobic, misogynistic, religiously hateful bigot. So please remember the importance of your voice every time you think of leaving--and do consider a break instead. A timeout could help, I think, and make the forum more fresh for you when you're back.
Best of luck. I have found this place of significant benefit over the years, but if some of the posts' negativity outweighs any benefit to you, maybe it's time for a break until you feel that the benefit will again outweigh the negativity.
Cheers.
