While they are still children, they are more of a potential problem. Of you don't think it matters whether they are kids or adults, why do you think they are messaging it that way? Do you think it just doesn't matter to you and it does matter to others, or it doesn't matter to anyone?
If it's the first, then that should make it matter to you. The more people that take the fascist problem seriously, as it is, the more chance for resistance and change.
Absolutism and not understanding the nuance of messaging from them and others makes it harder to resist them. Comedy and accuracy are important tools against fascism. The only power is the power people give them. Remove that legitimacy and they lose the power.
