You aren't a liberal for being human. It is something to remember that some of us are not the best "people person" types and either need to work on that more, or need to find others who can better do those roles. Using myself as an example, I'm good at being diplomatic, but chatting up strangers has never been one of my strengths; it's possible I could make it one with enough time and motivation, but right now, it's not. Not having that strength will cut off capabilities for me that people who can do that, have. I also have an easier time getting into meta, deep concepts than some, but it does little if I can't present it to others in a way that communicates its value effectively and contributes to the advancement of liberation and the advancement of more compassionate and stable conditions for people.

We have different strengths, in other words, and no matter what an individual works on, they will still lack in some areas. That's one of the reasons organizing together and complementing each other, in both strengths and struggles, is so important.
