There's always 3 parts of someone's politics you have to take note of:

1. Economic base (progressive economic system vs. status quo and reactionary economic system --> eg. socialism vs. capitalism)

2. Superstructure at home (culture + gov't issues --> eg. racial equality struggle + liberal democracy's struggle between elected and appointees)

3. Foreign Policy (critical support of ideologically-aligned gov'ts, if not strategically-aligned ones, against larger evils)

And if at least one part of someone's ideological thinking are very much hostilely contrary to the rest of 2/3, they should rethink their entire viewpoint on why it is so
