I've always felt that the framing of "don't give them a platform" is off as it's more like "don't make me support and amplify these things I really disagree with".

Different communities are good for different things and there is such a thing as community standards. It doesn't have to get to the Alex Jones political level either, just think like how weird it is when people hit on each other on Nextdoor [1] or if some guy was trying to sell his lawnmower on Grindr/Tinder.
