I disagree with several premises. I wouldn’t want my children’s shows to shoehorn in messages. If it makes sense in the plot for the characters to have and voice an opinion, or if it’s a cleverly written allegory, then that’s great. If they are just creating a character for the exclusive purpose of pushing an agenda (even one I agree with) it’s annoying.

Whenever someone says “people doing X, are the same people doing Y.” You’re witnessing some broad sweeping generalizations that are usually just the writers opinions. You can just remove the X statement.

I don’t like when protesters block my road on the way to work, or shove pictures of dead children in people’s faces, but I still can agree with protests against wars etc. Not liking the mode of messaging doesn’t equate to disallowing the massage and that’s fair. Personally, I encourage people to disrupt the actual power structure in place instead of the general population, but that’s just me.
