The only real moderation that needs to happen is self moderation. If you see someone saying stuff that you don’t like, block them. That persons opinions are now gone for all that matters to you. There’s boo need for their opinions to be removed for everyone. Everyone has the capabilities to moderate their own experience.
If someone keeps being racist and it bothers you, block them. If someone keeps name calling and it bothers you, block them. Those of us who aren’t bothered by opinions we don’t agree with or by people saying things we don’t like can still engage with those people and perhaps even teach (or learn!) something.
There should be very few restrictions on speech, especially in an online forum/community, imo, restricted basically only for trying to incite or threatening actual physical harm.
Your first instinct is that an assumed illegal immigrant is a trump goon?
