Everyone does this, it’s not unusual, but the consequences of doing so is naturally a leftist outcome. Leftism isn’t a random direction, with unrelated and disparate views, nor is rightism. Leftism is a selection of coherent and synchronous solutions to sets of problems using the same logical framework of analysis.

Leftism isn’t about “sticking to one train of thought,” and that’s a very myopic view of political ideologies in general.
