Sure, but that doesn't make you a bad person.

I grew up as a fervent GOP supporter and thought they just weren't able to execute because I lived in a blue state, and then I moved to a red state and realized the problem isn't with any given party, but the lack of accountability when they have a clear majority.

So I now consider myself libertarian and vote for whichever candidate has a decent platform in a given election. In my state, that's usually libertarians and Democrats, and for President, it varies by election. My vote doesn't matter that much either way, but I try to do my due diligence anyway in case I can influence others who live in more interesting areas.

I dislike both major parties, but both field decent candidates from time to time. Unfortunately, that hasn't happened for President in quite some time though.

I can't speak to phrenology per se, but phrenology's modern analogue is, in my opinion, the "genetics" argument. Whereas phrenology was some attempt to "explain" how the apparent shape was indicative of underlying brain structure, contemporary "scientific" racists will use genetic differences to "explain" whatever behavior they want to attribute to it.

Not necessarily phrenology specifically, but scientific racism is a thing. One example is Stefan Molyneaux, if you want someone to look up. The "science" these people use is often poor or extremely misleading.
