Why do most men in IT like to hangout with progressive girls, but want a traditional ones for marriage?

Ive seen a lot of men in IT who somehow want to hangout with the most modern and progressive girl. When asked, they say they don't vibe with such girls ( trad ones) . These men acted like the most progressive ones with feminist mindset, etc. But when they were looking out for matches in an arranged marriage setup , they looked for some one , let's say who would be a wife who serves her husband, dress modestly, doesn't drink or smoke ,etc( the exact opposite of how they acted).The shocking part was ,even the married ones who already had such traditional wife was looking for the most modern girl to cheat on.

What I don't understand is, when they feel they don't vibe with such women , why marry them? And then why cheat on them again? They're literally breaking hearts of both type of girls.

PS- I'm here for perspective not gender war.

Edit - I'm starting to like the men in this sub, y'all are giving calm responses. I was torn apart in the other sub 😭
