Liberalism is based in the teachings of Jesus Christ and was always intended to keep governments from interfering with the personal relationship between each human and God.

It fails when people prioritize liberalism over the Word.

For example, feminism runs counter to scripture and so should never have been allowed under Liberalism. Same with gay marriage, the whole tranny thing, even allowing pornography as "speech".

Everyone always forgets that Liberalism is only justified by the fact that God created us in his image and we each have a personal covenant with him.

If we're working in an atheistic "we're all mechanistic automatons" framework, Liberalism makes no sense because we're no different from anyone else and should all be forced to bend to the most powerful authority.

Similar for Muslim and Judaic religions; they're tribal and believe they are special to God bjt everyone else is a slave; neither should be tolerated in a Liberal society.

Liberalism isn't failing because it's a weak ideology, it's failing (just like every other ideology these days) because everyone has the idea that God is obsolete.
