Absolutely !!

It is good for people to experience religion for a point of reference, but children are forced to it and it is the primary way religion perpetuates itself. Applying religious propaganda to children and rewarding suspension of disbelief (Santa Claus, EasterBunny) in relgious context is kind of messed up,

I don't believe that teaching children religion is automatically abusive. I believe it can be, in some circumstances. When you're shunning, disowning or beating your gay kid, or sending them for conversion therapy because of your religious beliefs, then you've crossed the line into child abuse.

Parents still have a right to influence their children's beliefs (political or religious) to reflect their own. I don't believe in a nanny state, taking that right away from them. I do believe in an education system that provides balance and counterpoint, and encourages freedom of thought.

Being forced / required -- yes, tis bad --- explaining and selling the basics (even w/ a bias) of a belief system -- not so bad, but still marginally bad --- openly discussing the pros/cons and why one believes - OK -- but I'd bet that nearly never happens

Richard Dawkins says, and I agree, that teaching a minor any religion is a form of child abuse.

Of course, its grooming

Being forced into a religion is abuse.

Being forced into a political party is abuse.

Being forced to believe x is abuse.

Not IMHO.
