Thats a baseless claim, not a fact. Just because you think men are more tolerant, doesn’t make it so. Either you can prove it with some evidence, or it’s just your own opinion.
My relationship so far is great with my in-laws. I have no problem with my MIL, shes a sweetheart. That doesn’t mean I should be living under her roof though. I don’t expect my brothers wife to live under my parents house either. Adults need their own privacy and shouldn’t have to live with parents.
