The whole Chris Rock/ Will-Jada Smith thing was a preplanned Hollywood stunt, brought on to bring awareness to a failing show and a disease that had a new medicine being introduced at the same time. It wasn't toxic anything, more than Hollywood.
As for toxic femininity or toxic masculinity, eh there are toxic Christians, and toxic non-Christians, toxic Jewish people, toxic Muslims and toxic Hindus I am sure. The point is, it's not being feminine or masculine that makes one toxic, it's deeper than that one aspect of a person's life. It's a toxic heart.
Why is Jada so toxic? Because she needs Jesus. Why is Will so angry? Because he needs Jesus. Why is Chris Rock so mean spirited in his jokes? Because he needs Jesus. Why is there marital strife, pride, anger, theft, murder, immorality and a host of other issues? Because we all need more Jesus. This is a fallen world, and there will be no true justice until we see Jesus, so questioning these things is useless unless it brings us all closer to keeping our focus on Jesus. Life isn't about our happiness. Life is about trying to become the person Jesus wants. We are supposed to die to ourselves, because we were created to be used by Him, not to be comfortable or satisfied by the world.
Eh but that's just my opinion.
