In Offering to share my umbrella without sounding creepy op, assumed to be a man, shares an umbrella with a woman because it's raining a lot. For some reason good portion of the response to this question revolves around flirting.
Given the situation, I don't understand why this is considered flirting at all. Furthermore, the top answer for this question mentions giving the woman the umbrella when she wants to part ways so she won't get wet. I'll be honest. This move is pure class from my point of view. It's just something you do if you're not going to walk another couple of miles in the rain. The issue is that in the last sentence of this paragraph the answerer mentions a date being a possible result of this action.
What followed this was a bunch of push back from who I can only assume to be women about how this was bad. None of the people who had a problem with this actually engaged with the act of giving someone else an umbrella. All of the comments were about the inclusion of a possibility of a date being a massive problem. Even the mod who deleted said string of comments asked for it to be removed.
Why is the suggestion of a date being a possible outcome of an interaction so offensive?
There are a few other answers to this question which also state that op seems to have been flirting and such kindness would have made the answerers uncomfortable. I just don't get it.
I tried to hash this out in the comments, but this doesn't seem appropriate to discuss there for whatever reason.
tl:dr;
Why is the suggestion of a date being a possible outcome of an interaction so offensive?
