I don't know what are the burrs under saddles on either side re 'grooming'.
But let's use that as an example.
But I suspect there is a difference between arguing why you don't think things like transgender studies and such is not pedo/grooming and advocating pedo/grooming? Certainly it should not be okay to accuse a member of being a pedo or pedo groomer or any other criminal activity, but there is a difference between that and saying a person's position is soft on or forgiving of or supportive of that which results in criminal activity.
I constantly train newbies on Twitter to get it said when it is important to say, but take care in how you say it. There is a huge difference in objecting to a vote that would make pedophilia a lesser crime and accusing a person of being a pedophile.
It is one of those subjective nuances mods have to use all the time in these situations.
