I am a very liberal person and I have very liberal children, except for one. I'm pretty sure my Gen Z son has been taken in by fascist doctrine. What can I get him for Christmas?
Doing political stuff for Christmas is one way to ensure you have a nazi kid forever. Just ignore the politics, give a normal gift. Love will conquer all the hatred that he has. Good luck.
Not only that, but the hatred on the right will consume them. Sit back, lay low, don't participate and let the fools burn themselves. Opposition will only give them targets to blame for their failures.
Being conservative depends on you being fearful rather than empathic. The fast way to get people to turn from conservatism is promoting behavior that is focused on doing good for others and providing an environment where someone might not have as much external stressors triggering a fear response.
Love conquers all? This isn't a Hallmark movie, yo. Have a chat after Xmas. If you have the presence of mind to see your kids supporting shit we literally fought wars over, you don't pat them on the head and say "ah it'll be fine".
