It will be prevalent long into the future, don't kid yourself. Opposing view points on all subjects will always exist and these arguments will always happen. Instead, you should be shocked when violence or vulgar language is still being used to exert opinion dominance.
The fact that many people might share your desire and tendancy to disrespect others doesn't mean that I should accept your nonsensical, prejudiced arguments as a necessary fact.
The base argument that you are using is the same that has been used to validate the chastisement of many minority groups .. in fact all minority groups have campaigned for the right to be referred to using terms that offer respect.
Making a 'stand' and arguing for the right to disrespect someone is far more dangerous than vulgar language will ever be - and I'd also argue that it's more disruptive than violence, as it has an effect which is longer lasting and is more likely to prevent lasting positive change.
Is the other person not disrespecting me when they ask me to refer or participate in their choices that I might not agree with? Why is it that when someone deviates from the norm, everyone else has to respect them while they do it?
