Sorry you have to deal with these people who want some small independent content creator to take a stance on world issues that are far beyond the scope of the average person who takes part in these kind of communities. Everyone who joins your site with the goal of interacting on a discord server should be well aware already of what you stand for and what you want this space to be.
Good on you for explaining yourself but i fear the people who throw these accusations at you will not be deterred by these words, hope you can just remove them from your community if they get too annoying.
