You say, “it’s not Republican men who are refusing to date liberal women.”

The WaPo piece says, “A 2021 survey of college students found that 71 percent of Democrats would not date someone with opposing views.”

Notice it does NOT say men or women. It says “Democrats”.

If you look just above that, you'll see that the article is specifically pointing out the imbalance between women and men being along political lines:

46 percent of White Gen Z women are liberal, compared to only 28 percent of White Gen Z men, more of whom (36 percent) now identify as conservative. Norms around sexuality and gender are diverging, too. Whereas 61 percent of Gen Z women see themselves as feminist, only 43 percent of Gen Z men do.

This mismatch means that someone will need to compromise. As the researchers Lyman Stone and Brad Wilcox have noted, about 1 in 5 young singles will have little choice but to marry someone outside their ideological tribe.

Combined with their observation that it is Democrats who will not date non-Democrats, it is they who would have to compromise by the article's logic.

Dishonest reporting would argue that the WaPo piece absolutely says conservative men should become Democrats

Except the article explicitly says the opposite of that:

about 1 in 5 young singles will have little choice but to marry someone outside their ideological tribe. The other option is that they decline to get married at all

They explicitly spell out only 2 options: either not marry, or marry across political lines (which the marriages would not BE if the men stopped being conservative, since they'd then both be liberal). It literally does not leave open the possibility of either side changing their political stances.

Instead it called out for people to open their minds and try to consider how another PoV might see things

And what do I see in this thread? People who refuse to consider alternate perspectives.

This is just infantilization of GenZers. What are they (or you) basing the assumption on that GenZers (and I) have not considered the other sides? Just because we don't reach the same conclusions?

Sorry friend, but just like you I also have conservative family members (some for religious reasons, some for political ones), and I think that aspect of them makes them pieces of shit (even if I still love them as family) precisely because I know their motivations and their reasons, and those reasons aren't good enough to excuse their beliefs.

I have considered alternate perspectives, long and hard. I just don't agree with your conclusions.
