It sucks that some liberals have tainted the lefts image though, as someone on the left, it's evident there is some obvious misconceptions about the lefts stance on freedom, as we've always stood against authoritarianism and other forms of oppressive hierarchies. Liberals aren't on the left though, they've always been right-leaning centrists, as they are in support of Capitalism, a right-wing ideology.
Saying "political correctness" is the biggest problem in society is incredibly short sited though, the alt-rights increased mainstream acceptance, especially on the internet, is a far greater threat to freedom than someone being offended or some protests against misogynists.
