You probably go triggered just because your reply got delete and now you think the forum is having 100% pure partisan politics. What is really awkward is that you realize the thread is self-moderated, but then for some reason you still think it's the moderators deleting your posts.
For starters. What do you think "Self-Moderated" means?
it's probably for the dramatic effect and to make himself look like a damsel in distress for being "suppressed" by the forum because of his views.
2. It is self-moderated, and the moderator systematically removes any post that criticizes Trump in any way, or defends the Biden administration in any way, etc.
are you 100% certain that the mods are the ones removing the posts? I mean, as you said, the thread is self-moderated, meaning the person who created the thread can moderate it.
