And to reiterate my stance on sexist tropes: I deny they exist. All it takes is to reverse the genders playing the roles and it's fine again? It never was problem to begin with then. There is a clear line between sexism and old themes.
There is no reverse gender trope for any of your examples. If a reverse trendered trope emerged, then yes, it would still be sexist.
You seem to be fundamentally incapable of understanding the different between a narrarrative element and a trope though.
Mario rescuing Peach is not sexist, anymore then Peach rescuing Mario in the reverse version. The
trope of the damsel in distress IS sexist, and Mario rescuing Peach is an
example of that trope. There is no trope for strong, heroic women rescuing a weak and helpless male with no sense of agency. It doesn't exist. It may happen occassionally, yes, but it
is not a trope.
It could be a subversion of the existing trope, sure, but it is not a trope in its own right. So let me repeat this, in the hopes that you will be able to figure out what the actual problem is here: It is not the occurrence that is sexist. It is not the intent that is sexist. It is the societal, cultural force that arises when those occurrences are promoted to the standing of trope that are sexist.
It is not sexist for the male hero to rescue the damsel in distress. It is sexist for that to be the
standard - and it would, in fact, be equally sexist in reverse!
You keep denying sexist tropes exist, but have yet to provide a single shred of evidence against the existence or sexism of the sexist trope "damsel in distress", though you seem to think you have. At this point, I am only able to realistically interpret what you are saying as "I do not know what a trope is, nor do I understand what sexism is." And okay, maybe that's true. But let's be clear - you appear to be operating from a position of ignorance. There are valid arguments you could actually be making here, if you really do want to oppose this line of thought, but you're going to have to actually understand the topics being discussed before you can get to those...
