Again, instead of gay if she was spending a bunch of school time to explain tenets of Christianity or Islam with the kids, would that be evangelizing? If "groomer" gives you pause, then how about evangelically gay?There's not such thing as liberal or conservative kids. Their parents, sure.
There should be no "grooming" of children to a lifestyle or ideology. Where we disagree was the weirdo preschool teacher. You say she's "grooming" the children. I, however, think she's trying to teach tolerance in a really hamfisted way.
She's probably a shitty teacher. But not a groomer.
She is seeking converts. (And I don't necessarily mean turning them into some other but she is proselytizing to get them to join her worldview. She is an indoctrinator.)
