While I know people have complaints about how it sometimes infantilizing and played for laughs et cetera, when I first watched Big Bang Theory back 2007 or so, it felt both like an eye-opener and deeply validating.
Sheldon doesn't mask. He is not anxious. He is not ashamed of who he is. He never "learns to chill and be normal". He is helpfully insightful at times. And he retains close friends who repsect him and he keeps a successful career. That was beautiful to see.
It made me believe I could exist as myself.
I know the "front lines" have moved since then, and most people expext more from representation, but I will ever be grateful for what that series gave me.
