Making my case against your contributions (but not against your person)
Several things regarding your controversial additions that I intend to see deleted or otherwise corrected.
You have insisted on there being an article simply titled "Bronies", rather than any variant that distinguishes the subject as NOT being representative of the entire subculture, although you do acknowledge in the article itself that not everyone in it is "bad" by your criteria. Going by your logic there, we should have articles named "Muslims", "Black People", "White People", "Jews", etc. I should not need to explain why that is wrong.
The picture you uploaded of what you claim to be a "typical" brony clearly demonstrates your prejudices and true (though possibly subconscious) intentions, despite how you may attempt to justify or add nuance to them.
You have stated that you wish to keep both articles on the two "sides" of the "conflict" in question for the sake of being balanced; that is like having a "Jews" article so as to be "fair" towards those who support Antisemitism, or a "Black People" page to remain "neutral" on racism, etc.
Your main reason for justifying the existence of articles on Bronies, etc. seems to be that you find sexualization of animal or underage characters gross. That is fine for you to think, but to impose such a judgment on others and label anyone as even remotely "villainous" for their sexual tastes (which are distinct from any offensive sexual actions ) is wrong, and is akin to adding and defending an article on "Homosexuals". Sexual deviancies, when they do not cause actual sexual offenses, are "merely immoral" at worst. Please understand that.
Many of your other comments, including one implying that "furry–ness" constitutes "mental illness", further confirm your prejudices/bias. I acknowledge that your expression of these prejudices is not done with malicious intent, and do not condemn your entire person for your objectionable beliefs, but the way and context in which you are expressing them here are not acceptable, and I, again, intend to continue making the case for having that fixed.
