I think that’s a massive, massive overgeneralization. I don’t think that gender makes a whit of difference in this. There are plenty of women who don’t care about the actual wedding. My 24 year old daughter just got married in jeans in front of a judge, which was her choice. I myself didn’t care that much about either of the wedding ceremonies I had for my two marriages. Both were in parks with a minimum of fuss.
I think that it’s toxic gender roles and false ideas that are “sold” to women that makes them fixate on weddings. Also, the more we falsely tell women that they must have no lovers before their husbands or they’re “damaged,” the more of a big deal the wedding has to be, with all of the misogynistic crap about the father “giving” the daughter to her husband and other offensive garbage like that. Women who are empowered and make their own decisions are usually not all ‘bride-brained” and nuts over the convention of the wedding ceremony. That’s my honest belief and my honest observation.
