I mean honestly, this sounds like a “you” problem you’re trying to get the devs to fix.
You say the people that disagree with you are psychos not worthy of your attention yet you let them affect you to this degree. Why not just flip the switch in your mind and say “idgaf about people who disagree with me on this” and just keep doing your thing. A lot of people already do that here and the downvotes they receive do not seem to distract them from persistently espousing unpopular views.
If engaging in online platforms like this and getting downvotes for perhaps unpopular opinions is harming your mental health, again this is very likely not the place for you. In all likelihood you are not martyring yourself for a particularly good cause. A lot of folks online here are not necessarily going to be here looking to have their minds changed or discover deep universal truths.
Many are probably here to throw a quick vote against or in support of something and maybe rile someone up with a curt reply for laughs. Being able to engage with content in a non-committal way with votes is a big appeal of platforms like this and Reddit.
One of the reasons Digg died and Reddit took over was that they took away the downvote feature in one their ill-fated redesigns. People like downvoting stuff they don’t like probably more than upvoting things they agree with. If you take that away, you’re taking away at least a good 80% of your audience that likes that stuff.
If you are only interested in pure discussion without votes, your best bet is to find an online forum without such a feature on the topic you are interested in discussing. The audience will undoubtedly be much smaller or perhaps be non-existent but may suit your needs a bit more.

































The char on that meat looks incredible. Well done :o
