I'll get into the refereeing you two below in a second, but I'll respond to this like the ornithological boxer that I am. There's a wider point here - Fuentes wasn't news over here, now he's part of the global conversation and condemnation and support is being handed over freely from here and from the EU. I'm not sure why, what I do know is that we have now platformed a fairly douchey fuckwit who didn't need to be platformed and that platforming was done by performative feminism (at least in my life that's the been the experience, but I can't generalise).
The way the Fuentes storyline has been played over here is a bit more centrist. Namely, he was doxxed online and a woman who lives in the same town went and knocked on his door to ask him some pressing questions she had. This was stupid. Fuentes was hanging around in the penalty area trailing his back leg waiting for a defender to clip his ankles and now he's gone down like a sack of shit. The Dems are playing it off the way you have, but that's not how its being reported to moderates - and the way things are reported matters. This was giving away an unnecessary penalty if you'll excuse the soccer analogy.
And yes, I can imagine there has been an escalation in the gender war - there has been for some time. My teacher school friends have reported this happening on both sides, with boys making overtly sexual threats to girls, and girls threatening to report boys for sexual assault when relationships go south (which they do incredibly quickly in teenagers) - the question is 'how do we take the heat out of this for our youngsters?' - not 'which flavour of youngster is worse?'. We both know the answer to that given the relative size, strength and political milieu. As I wrote in the last article, the Dems have been handed their ass on a platter by overly focussing on identity and as many people (and not just me) have suggested, by making men the blueprint for villainy. Professor Scott Galloway did an interesting analysis that's well worth reading.
Free speech is fine. I think everyone can say what they like - but if we take every utterance by every fuckwit as a talking point, society will eat itself to death. Let him say what he wants and anyone left of his far right wing base shouldn't respond at all. Ignore him. Not because he'll stop talking but because he'll become 'a loser' in the attention economy. Put him on the collective naughty step. I'm not saying people can't issue free rebuttal after rebuttal at him if they want - say whatever you like - just be cognisant that it has never worked in the past, the election has demonstrated it is a losing strategy and he probably likes it.
As for outrage, I go back to my penalty metaphor. The Trump organisation needs only one person to act as a synecdoche for all blue-hysterical justice warriors. The left continually churns them out - moral crusaders seizing the moral high ground in an endless display of pyrrhic victories.
