I remember a year or two ago, the wife's cousin and cousin's husband came to stay for a bit (from the USA).

Both the cousin's husband and I were given strict instructions not to discuss politics, and I was further informed that he's a Democratic Party activist over there.

Needless to say, we ignored our orders, and got along famously, to much eye-rolling from the wives. Turns out we're both very critical of government corruption and overreach, especially on censorship, and he's an absolute loony gun-nut in a country where that's legal. He's promised to take me shooting if i visit.

People worth knowing are individuals, with their own unique "fingerprint" of views.

My personal pet conspiracy theory is that people who give a damn and are willing to give real thought to big problems secretly have more in common with each other than with the other 95% of humanity. But most would rather be waterboarded than admit this :p
