You lift weights because you have body dysphoria. Either you're skinny or fat or some other undesirable body type and you want to become /fit/.

I too have body dysphoria, so I use estrogen as a means of redistributing body fats to more feminine areas like my thighs, butt, and tits. I'm a short, petite femboy -- estrogen enables me to become more /fem/.

On the surface level it may seem that our body modification goals aren't comparable, but this is far from the truth. We (100% of the human population) have experienced body dysphoria at least once in our lifetime. Making laws regulating or limiting my access to estrogen is like banning gym equipment.
