The whole thing about getting older and having more experience is that eventually you become better able to understand, handle, and accept things that would upset you greatly when you were younger. These things may not make you happy, but they at least don’t completely derail every fiber of your being, causing extreme upset and anger.
That’s what growing up is. And that’s something to be happy about, damnit. :) We humans improve mentally with age, as our bodies deteriorate horribly into pale shadows of our youthful vigor! (Hyuk hyuk.)
The sentiment that you become able to handle past injustices better, that you dwell on these injustices less, and that their impact on your life is lessened as you get older isn’t transphobic. It’s a testament to the ability of human nature to grow and improve.
I apologize if I offended you because I stand by this idea as a whole. If you don’t get better at handling problems as you age, your life is destined to be pretty awful. Luckily, every human who has ever ceased to throw a temper tantrum when an ice cream cone falls on the floor has already demonstrated that their ability to handle problems has improved over time. And thus, I am reasonably certain, based on my experience and observation of others, that in five, ten years’ time, the things that hurt a giant amount right now will hurt less. This is part of life. One of the better parts, in fact.
Additionally, not every discussion in which people don’t agree is an argument. :) If all my friends agreed on everything, it’d mean I picked pretty poor friends indeed. It’s never good to surround yourself with people who think the same as you. The fact that this has been labeled an argument when it really isn’t is very troubling! But, troubling as I might find it, I am not upset. Because there’s no point in being upset at people you love. <3
