Are people so opinionated?

I know this is supposed to be an open-minded site and all, but I noticed when some recent subjects are touched, there is a VAST controversy where people suddenly become defensive over an issue that really isn't a big deal.

For example, let's take "gay" for instance. Most people here I know think that being gay is not a choice, and is instead something one is born with. This issue used to be heated years ago, but lately people have become more accepting of gay people.

Now a new issue in the past few months I noticed arose that just astounds me at the reactions given on it that really makes me question if most of the people here on is it normal are really who they imply they are to be (open-minded, for instance).

One example I'll use for now is with bronies. Just in case you don't know what a brony is, let me explain it right here with the most commonly accepted definition:

Brony - a male/female fan/viewer of My Little Pony: Friendship is Magic that remains outside of the target demographic the show originally intended for (kids and parents as opposed to young men and women).

When this issue gets touched on, I notice some people go into "Gay Hate" mode all of a sudden. Now suddenly, people lose their open-mindedness I saw earlier and start becoming strangely hostile ("Only faggots like a girls show, for instance"). Note this is just a minority here that are doing this, but it still bothers me when I see this kind of stupidity. This is just one example of people just outright attacking a new phenomenon (it really is something that needs to be discussed more in my opinion, I personally find it fascinating) with the utmost contradictory appeals.

It's like a TV show can literally make people want to have homosexual relations now with another man right? I thought only Twilight had the power do that...

Here's a quick story that lead me to start this Poll Question:

I recently had a conflict with a guy I know on Steam. He suddenly messaged me out of the blue with "are u a bronie?" I then asked him, "If it means I just watch FiM, then yes." I was instantly attacked with varying insults from "ARE U REALLY GAY?" to "THE FUCKS WRONG WITH YOU!" Me, remaining calm (and laughing in reality), asked him "What if I told you I'm female?" to which he replied "I'M SO SORRY!"

Even though this conversation I manipulated caused me to get a good laugh, I was disturbed that this generation still thinks some shows are restricted to a certain audience, and that being a man and watching a girly show or a show about cooking, for example, makes one gay. Haven't we gone over this? Just because I watch Man vs. Food, doesn't mean I'm fucking fat. I'm actually quite the opposite.

Note, I'm not trying to restrict this issue to just bronies or homosexuality, but to a VERY GENERAL level. For instance, the issue can even extend into things like religion. Some Christians state how the Bible should be read in schools, yet they obviously wouldn't want the Qua-ran to be read alongside it. They are obviously picking sides based on their belief system and that is clearly irrational. You can say I might be over-thinking the issue, but I think this is a MAJOR flaw with the human brain and it's thinking system. We restrict ourselves to one end and refuse to leave that closed-minded state. This is something I feel MUST be eradicated from existence if we are to advance further.

Teaching kids stuff like gender roles, down to which sex we should fuck... It's all been just bullshit propaganda to me that brainwashes our generation and limits our free speech in the long run.

It reminds me of the quote; "Children are just stone slabs just waiting for someone to scribble on."

In my sole opinion and conclusion, I could come up with a million words on how stupid and opinionated we actually are; I'm just wondering if anyone else here thinks the same.
