Car companies. They just make the community so toxic that the car-heads will never listen to anything associate with the group. They also use tactics like make in and out groups so you either belong or you're one of them. Here we're family.

But the best strategy is usurping groups by helping the most unpalatable people rise to the top.

Ask yourself who was the last charming social justice advocate? Its probably been decades.

Bugs bunny nailed it when he said "if you can't beat em, join em" there is more bang for the buck by creating and promoting unpalatable groups then there is in fighting them.

Oh the car companies probably, I'm not saying it's happening but it's an age old tactic to fund groups with extreme options, you hype them up into saying things like 'no one needs a car' then you put in your other hat and go over to everyone else saying 'look at this crazy, they say no one needs car but that's because the don't understand rural areas/ disabled people / women / trade workers... (Delete as appropriate for the person you're talking to)

Then if they hear a sensible argument against cars the man in the hat says 'oh they're trying to sneak in the fuckcars stuff my the back door, remember how they want to take your car away because they don't care about your situation...'

Again I'm not saying this is what's happening, I'm just saying how a very common tactic of PR happens, the oil companies have done it loads.
