Majority bias. It isn't unique to majority-white places and everybody will be familiar with in-group/out-group bias. It also frames it as a property of the society in question, not something the individual person possesses.

Instead of 'male privilege', "equality" or better, "equity".

For "toxic masculinity", I like, "machismo", or better, "toxic machismo", since not all sorts of masculine pride are harmful.

Yes, I suggested that what I've seen be effective is suggesting that white people imagine their struggles, but with the added burden of aggressive policing, employment discrimination, housing discrimination, and racism in general. There's no need to drag the term "privilege" out of its academic context, because it has the baggage of many connotations in vernacular usage. That is, just don't say the word privilege.

Other commenters have offered some good suggestions. Instead of "toxic masculinity," I'm partial to The Man Box, which frames the issue as discussing the outside factors that trap men into negative behaviors, rather than implying that they themselves are bad or broken. Wherever the problem actually exists, men are much more receptive this framing.
