Have you found this to be true? It seems like liberals are almost always outspoken, while conservatives by-and-large keep their beliefs to themselves. Liberalism is "safer" to express in most social settings, and it also places a high value on evangelism. I think this is kind of a whitepill. A lot of people become demoralized after seeing all the liberal messaging around them. It helps to recognize that liberals are just a lot more likely to speak, and that the silent majority often harbors conservative feelings they're too hesitant to share.
