“Leftists claim it’s anti-LGBTQ+....”
If they are doing grooming and some are, Tough. If their apologists protest Tough!
If you think about it ...
LGBTQ+ is blatantly anti-hetero and anti-traditional marriage, - they don’t even have a letter. Use of the letters excludes and rejects hetero and traditionally minded folks. In practice, the latter are “welcomed” if they kowtow to the perverts, their agenda and practices.
The cat is out of the bag - grooming is a very important part of their cultural operation. This is another battle to control language, which then controls thought, which controls behavior and punishes those who step outside the controls. The right should continue to call them groomers. They own it.
