This started in the 80's and 90's with shows like Married with Children. The father is the stepping stool for the family. This is a 180 from 60's and 70's tv with fathers like James Evans sr. and Archie Bunker.The problem isn't female characters. There are plenty of female heroes in marvel comics and there was always string capable women in the MCU such as Peggy and Sharon Carter, maria hill, lady sif, gamora, wasp, shuri,. Ami, the Dora's etc. The problem is his they've been written as of late I'd say going back to Ant-Man . They are introduced in main heroes title and the hero gets outshined by her and is made to look like a bafoon as seen in Loki, Thor Ragnarok, Ant-Man, black widow is a perfect example with how they did red guardian.
I don't completely fault marvel studios for this because it's more of a forced pandering and they are doing it to save face. I read it here in some thread prolly this one that somebody at marvel tweeted something sexist so to save face marvel started gender swapping heroes and villian etc. I think it was also said the pandering is due to feminist nagging Kevin feige because if the success of wonder woman at DC.
On a side note I want to be interested in Thor love and thunder. The little that I read of Jane foster as Thor was good bit since odin is dead we prolly won't get the same story beats from the book. Especially since this movie is being helmed by taika watiti it will have a light hearted approach and won't deal with heavy handed elements like Jane battling cancer and depending on the lower of their to sustain herself. Also I'm sorry but I don't want to see valkeri and korg. I'm tired of lugging at Tessa Thompson's pug face and korg is not funny at all besides Asgardians don't love those rock people, why is Thor hanging out with him?
It's a comedic trope, nothing more nothing less. Think about how George Jeffersons MAID would talk to him like he was trash. This would never happen in reality and was a way of introducing a comedic element into the series.
