I think I mentioned that the extreme left side of things also had hateful adjacent messaging. But I personally haven't observed as much of it, and it also doesn't seem there is a big enough market on that side for a startup to capitalize on. Maybe I just never heard of them though?
I'm personally more centrist overall, but I've tried as much as I could to give an unbiased summary, though being unbiased in those cases is hard. I'm trying not to judge the behavior, just observe it.
One thing I have observed is that the current moderate left in the US does seem to align more with Canada/UK/France style of free speech, with a broader definition of what is considered hate speech and stronger enforcements against it. Where as the right seem more aligned with the traditional American view on it, where hate speech is limited only if it can be shown to have directly and immediately caused lawless action.
This seems to be the crux of the issue as well. With the big social media platforms available today, it has enabled hateful speech to have more reach at a wider scale than ever before. It also enabled not only Americans to reach others, but even non-Americans can promote and propagate hateful messaging in a targeted and strategic way. The question is what if anything should be done about this, could it lead to instability and divide and throw the country in turmoil, or maybe it's actually a good thing and will allow more voices to be heard and considered.
It's the age old trade off of free speech and restricted free speech. Where do you draw the line? What risks are there on either side of it?
And my observation has been the right leaning Americans seem to still consider that there should be no regulations on this, and everyone everywhere, even non Americans, should be allowed to freely share, promote, upvote, and target any message they want, even hateful, no matter the intent behind it, because upholding the right to speak up and against the government is more important and so we should stay as far as possible from threading water or any slippery slope.
And my observation is the left leaning Americans seem more cautious, and think some regulations might be needed, to make sure that no bad actor takes advantage of this, or that discourse doesn't rely purely on emotions and hate targeted reasonings. And that not doing so would actually bring more instability and chaos, and the risk of threading the line between restricted but still free speech and non free speech is worth it, or maybe an exagerated concern, where they don't think in practice it would be difficult to distinguish dissenting views from hateful ones or those with bad actors behind them.
