Why are leftists unwilling to confirm if I should lose trust in leftists or leftists?

When it comes to the subject of trans people, leftists are often quick to use right wingers as example of people they think are wrong and should not be supported, because these right wingers supposedly have tge wrong opinion on trans people. But what about leftists who are wrong?

On one side, you have leftists who claimed men can’t get pregnant, back during Roe V Wade. Which obviously implies that if a transman (a woman claiming to be a man) had the ability to give birth before she transitioned, she is not a man.

On the other hand, you have the leftists who claims she is a man because she says so.

Now, why won’t the leftists who willingly use the subject of transpeople to dismiss or attack right wingers for their opinions on the subject do the same to their fellow leftists?
