As much as I like anime, there some tropes/jokes/cliches I'd rather do without:
The 'lol she's so bad at cooking that KOs people, so everyone's afraid to eat it' trope
The 'guy trips over and accidentally lands with his hands on someones boobs' trope
The 'scary, freaky, gay stereotype that doesn't seem to notice that people think they're a freak' trope
The 'cool rival' trope.
The sexualisation of minors in general is offputting too
Most anime is made for teenagers or little kids. Many of the tropes you mentioned are just because of a 10 year old needs to watch demon slayer and immediately understand what’s going on. One exception is the gasping/panting/etc isn’t a trope, that just something Japanese people do a lot. It’s just exaggerated in anime since the medium is a self referencing simulacrum of real life. Miyazaki during his famous rant about the industry talked about how people don’t produce characters based on people, but rather how they are based on the characters based on people. Add in a few generations of this and you sort of get to the heart of why most anime is fun, but nothing in it is real and the whole industry blends together except a few things daring to be different.
