Aight so let's get a few things out of the way before we begin. First of all, I'm not defining nice guy as the fedora tipping sociopath who will message you 15 times before calling you a fat ugly whore who he doesn't want to date anyway. I'd class that in the "bad guy" section. And bad guys, well I'll get to that later in this post. This is more or less just my opinion of what classes as a genuine "nice guy" and a "bad guy". This was inspired by the post "Why I dated 'bad guy'" by @Hannah591 Some people were commenting about the whole argument about nice and bad guys is dumb because no one actually defines them and nor does she, at least very well. So Imma do my best here to give it a go and hopefully y'all will at least find it interesting. Also I'm not trying to tell you should or shouldn't date, that's up to you and your judgement of the person. This is just me giving my opinion on something nobody really seems to be able to define. Also this can mostly go both ways, though I think some things differ by gender (on average).
Niceguys vs Nice Guys
You probably all know the meme of the fedora tipping neckbeard niceguy who acts nice to women and expects sex in return. Think Ross after season 6. The are the kind of guys I would class as bad guys, because that is what they are. They are the bad apples, the sour candies, guys whom it isn't healthy to be in a relationship with. That is how I'd define a bad guy. Nice guys then would, logically, be the opposite of that.
When I think of a genuinely nice guy, I think of someone who is just a nice person, not because they expect sex, but just because being nice is just a good thing to do. Holding doors for people, helping people in general and just not acting like an over confident, self absorbed prick who only cares about himself. This doesn't mean he lacks confidence, he just doesn't go overboard with it. They are the kind of people who are genuinely chivalrous because there is nothing wrong with that. These are the kinds of people whom I believe you would have a happy, healthy relationship with because they are genuinely kind and polite people and there's simply not enough of those today.
I don't like the "bad boy" image, because it honestly just looks like some over confident, trying too hard to be cool pleb who would just use you for sex and then never call you. As I mentioned before, I also think the m'lady niceguys would fall into this catagory as well, they're just a different kind of bad guy. The kind where "bad" means what it actually means, instead of some way to make them sound edgy and cool. This is because I think "bad boys/guys" are not good relationship material whatsoever and a relationship with someone like that would be unhealthy and have some negative, possibly long lasting effects on you.
That's My Definitions
Those were all just my opinions based on what I think nice guys and bad guys actually are and the kind of people I'd be happy dating. You might have a different opinion, and that's totally fine. I'd be happy to hear what other people have to say and talk about it as this was fairly short as myTakes go and I'm sure I'm probably missing a few things.
