So what makes you assume if someone a girl or boy online if you don't see their face and only have a username to go off?

Its easy. If you read my answers you know I am a man as my answers are buch and powerful al;most hairy.

Where as if you look at Clones, clearly gental well thought out and caring so is a lady.

Do men and women type different? I guess I don't assume gender with text because I'm clueless about how different genders type apparently.

I will look at a username to get an idea though. Like I would think you are probably female because your username is chelsea.

I don't use emojis either. That's more an indicator of age, I suspect than gender. Aside from name, the ways I might tell, aside from taking someone's word for it, is if they automatically use male or female pronouns. Views on sexuality, such as seeing getting laid as a score, would strongly indicate male. But of course, everyone's different and not everyone fits gender stereotypes. In fact, I think a lot of people are unhappy in life because they feel they have to fit a gender stereotype.

My older brother was awesome. When we were younger, he could play with my "girl" toys all day with me and he enjoyed himself. He isn't gay or anything, but if he hasn't had a younger sister, he probably would have had guns and cars and such, but he wasn't into those things.

I'm rambling on tangents, aren't I?
