Is there any line of leftists that are either developing ways to use the same online tactics as the neofascists (eg. flooding every comment section with the same opinion to dominate the narrative, with real comments or not) or ways to render these tactics obsolete?
This kind of stuff is extremely effective, as the last decade has shown. Then, why is it that I only hear of the fascists developing and using it? Why is the left ignoring this efficient stuff?
Is it? I think the effect gets really overstated by people whose entire life revolves around online communities or who financially benefit from this being the case. I rarely meet someone irl repeat online fascist talking points, except ones that are sort of ambiently everpresent in the culture. Look at the anti-trans stuff, it's extremely unpopular in polling across US, Canada, and the UK, despite being probably the loudest and most widespread message both online and in traditional media.
I'd agree with this. Comment sections are usually regarded as being unhinged and not to be taken seriously.
