If liberals were not involved in heavy social engineering, I would agree with you. But they are involved in cleansing the native cultures of their political and economic targets.
For example, America used to have a melting pot National culture and everyone was exposed to American ideology, life and values in schools through history and civics. Our ideology was based in the original intent of constitution with the addition of being inclusive of women and minorities as amended. The ideology of American freedom was what united us. Our lives and values were to live independently, morally and lawfully as people need to do to survive and thrive in a constitutional Republic with individual rights and devoid of a police state.
Liberals replaced it with foreign and racial tribalism. They replaced the constitutional ideology delivered in civics and history with racist diversity in social studies which delivers the ideology of racial scapegoating, race based economic jealously and socialism - which is unconstitutional.
Liberals are responsible for the societial breakdown of the West that we are seeing.
In a way, blaming liberals for the behavior of individuals is like blaming "predatory lenders" for people making bad loans. But, maybe I am wrong.
It's true that kids are impressionable, and are spoon fed a bunch of rot. Then again, their parents allow it to happen.
I don't know. I think there is truth in what you say. I just don't like letting people off the hook for their own personal choices. I mean, I grant everyone the eternal peace and mercy I want for myself. But in the meantime, people need to man up and own their own decisions.
