I'd be surprised and a bit put-off.
I know that a few people have included in their response that, at one point in time, women weren't allowed to wear pants, so this is like the flip side of that. The former of which may be true, but there are no practical reasons as to why a large portion of men should wear skirts. It's not like they could do it for reasons of discouraging creeps who may try to look at their panties through pants. Maybe a fashion statement, but I doubt that would pertain to a large enough chunk of the population so that whole retailers would need to market skirts solely for men. Also, if men argue that skirts would be more comfortable for their balls or dicks if they're hung like a horse... well. Lucky for you, but there are pants for that.

It would be hard to do. You'd have to design and market them in a way that is seen as obviously not feminine and that would be seen as masculine. And you'd have to get male celebs to rock them. Personally, I would not oppose them, I have nice legs so it'd be nice to be able to show them off a bit more. I mean, if you look at a movie like TROY, Brad Pitt is dawning a skirt for the entire film, but I don't think anyone saw him as feminine or gender confused in it. And of course Russel Crowe does so in Gladiator with the same response.1
