This is the fallacy:
“If this tradition was good for the parents then it will be good for the kids as well.”
There’s not a lot more to conservatism and – as much hatred this fallacy deserves – it is also by far the best conservatism has to offer. Because, at least, it looks like it might make sense as some kid of a default rule. “Why change something that isn’t broken?”, is the most offered conservative response to, well, anything. And it should give pause (including the middle and all that) because what we share is valuable because it is what binds us. It should not be changed just because somebody feels like it, that’s dictatorial. The fact is that change is the one tradition that binds every single culture together. So, in conserving, conservatism degenerates so quickly in dictatorial behavior precisely because conservatism strives to abolish the very change that makes us uniquely capable to cope with the unexpected. It’s no coincidence that the outer edges of conservatism are plagued with convictions such as creationism. As it isn’t coincidence that the outer edges of revolutionary progressives are plagued with totalitarians. And that the next generations of those revolutionary people quickly converge to conserve (showing how evolutionarily stable conservatism is).
So I confess to not merely hating conservatism.
Still, it is a fallacy so let’s inspect in some detail the fallacy of conservative conflation:
