One of the main issues I've seen growing among liberalism is a refusal to appreciate categorically objective reason. That is liberalism is supposed to be an ideology that cares about who people are as individuals on the inside that counts, and making sure they're universally treated with equality. Conservatism, in contrast, engages in inductive reasoning to stereotype people, and expects people to fit traditional norms which in reality just satisfy the emotions of the powerful.
However, something strange has been happening lately. More and more liberals are behaving like anti-intellectual conservatives by denying objective morality. You see this especially from the indulgence of mass media, pop-culture consumerism that tends to mock "hipsters". What I find most ironic about this is despite how liberals supposedly clamor for cultural reinvigoration against anti-intellectual conservatism, these liberals are behaving anti-intellectually in the exact same way.
Another thing is many conservatives are hypocrites in claiming liberals are lazy bums who aren't willing to apply themselves to become successful. This is despite how liberals work smart through creative thinking, and conservatives engage in office politics, but lately, many liberals have been becoming lazy bums themselves while accusing conservatives of being "hard-asses" or anyone who isn't a lazy bum of being a conservative "hard-ass".
On the other hand, there's a very strange movement by feminists and multiculturalists against white male liberals as well which is remarkably similar to conservatism. Many conservatives seek to identify those in society who are weak, sensitive, thin-skinned, exposed, and vulnerable, and then just bully them around and call them lazy unless they're willing to satisfy work ethic. The problem is these feminist and multiculturalist "egalitarian" liberals are doing the same thing to white males. You usually see this when discussing equal opportunity in academia or the workplace. They identify people in society who were supposedly privileged (when they're really not because they don't share the same anti-intellectual attitudes of those who were prejudiced, so prejudice doesn't get redistributed to them). In turn, they get abused and neglected, and told to endure rugged individualism after the fact.
It's a very bizarre situation, but it would seem that liberalism has been subverted by conservatism.
