Guy here. I'll do my best to answer these as truthfully and fairly as possible. At first glance, some of them are actually interesting, and others seem largely trivial.
1: Yes. My campus recently had a group called "Students for Change" take over the political landscape of the campus. They were ostensibly a social justice organization, but many were seen as simply race-baiters. As a result, a lot of them were indeed called "attention seekers." Another obvious example would be Donald Trump; I think we all know he's an attention whore.
2: For me personally, no. Though I will say that a lot of non-feminists or MRAs here are rather flippantly regarded as smelly, overweight, basement dwelling virgins or RedPillers. So I think in some internet circles this applies.
3: No, but I've been called a bigot and a racist for thinking that Michael Brown was not a saint. The derogatory MRA title also applies to this: I've seen people be called this only for expressing a different opinion.
4: This is a good point; no, I wouldn't like it. Though I think this speaks to politics in general. I also don't want a climate-change denier heading the HoR Committee on Science. But alas, I can't vote him out of office.
5: Personally, no. Though I've heard anecdotes of exactly this. Of course, anecdotes always need to be taken with a grain of salt.
6: Also, no. This has never been asked of me, and I've never personally seen a man be asked this question either. Whether or not this is a common phenomenon or an isolated incident is unknown to me; if it's the former, then it should be addressed.
7: I don't fully understand this question, and I also don't watch a lot of shows with panels like the View or something similar. So I'm afraid I cannot answer this question appropriately.
8: I don't expect it, no, but it isn't unheard of to have a man's choice of attire outweigh his accomplishments. That said, it is kind of stupid to bring up fashion in rather serious situations, though I've personally only seen this sort of thing for like the Grammy's or the Oscars.
9: This is personally something I've never seen. In other words, I've never personally seen the term "girl gamer" used in a serious context. Most of the people I play with couldn't care less.
10: No, because I realize these people are fictional and thus have no bearing on reality. I'm not that self-conscious that I compare myself to imaginary people.
11: Some people have said that my shorts make my hips seem to wide (I like basketball shorts over, say, thinner cargo shorts). Though I will concede that this rarely happens to me.
12: Also, no. The only example I've ever seen is the whole "pencil sharpener" thing, but that's just a silly retort to the whole "master key" nonsense. Though I will say that being compared to an inanimate object is not unique to women.
13: Yup. Last year I left a frat party alone and had to walk, at 2 am, through a rough part of town. They texted me the way through to make sure I was mugged or beaten up.
This is just my two cents. Different people have different experience, though I will again say that some of them were more relevant and important than others: issues like safety and sexual violence are more important that the perceived "girl gamers" title.
