He is not disparaging the whole community. As you said “there must be zero personal powered vehicles” is not a position the community has.

You can’t say “fallacious arguments” AND “disparaging the whole community”

Only one of the two can be accurate. IMO it’s fallacious arguments, which is not a good reason to remove or ban IMHO.

The reaction to stupid arguments should be good arguments or education, not removal.

You assume a whole lot about the person, if this is the only mistake he made. Maybe its just a 15yo who seriously doesn’t understand the difference. If he has a (long) history of purposefully misunderstanding the point and derailing its a different story. If not you are banning him for a bad argument you don’t agree with. That’s absolutely power tripping reddit mod behavior.
