I can definitely go on /pol/, and I have checked it out a few times. But I don't think I would ever really engage with anyone and try to debate, I just know it wouldn't be productive or good-faith. The most I would probably do is post some info-pics or leave a link to a video or something.

Edit: occasionally I do debate with far-righties but idk if /pol/ is the best place to do so. I think it's good to take the occasional look at fash spaces though, for example I looked at thedonald today to see how they were reacting to the covid news. If anyone's curious, they're being relentlessly optimistic: "he's gonna get better in a week or two and tell everyone that covid isn't that bad actually"

Honestly I kind of envy their attitude, I know that to some degree it's forced and they're just putting on a show, but I admire that stubbornly positive mindset. Kinda sucks to be realistic and have to actually think about things instead of just being blindly optimistic.
