How is that coming up in conversation though? Do you see someone talking about SRS and immediately insert yourself and give your own opinion on something irrelevant to you, completely unsolicited? Because I don't think many trans people are asking random cis people about their thoughts on SRS, I can't think of any other circumstance that would necessitate you giving your opinion on something completely irrelevant to you if you, as you say "don't care if you do, or have that desire/feeling." You can certainly feel this way, but coming into a trans space so you can explain to them that you don't "understand it," for no reason seems pretty transphobic.
An analogy would be, if someone went up to you after you mentioned something very important to your identity, beliefs or who you are and started explaining to you how they just don't get it or can't understand why you believe or resonate with this thing for no reason. It's disrespectful.
It's good to see people's feelings of superiority have carried over from Reddit.
