How do you answer to transphobic people saying you’ve never socialized with the gender you identify as therefore you are not the one you identify as?

I usually try to answer to transphobic people who answer that questions that I simply know that I’m a girl. The problem is that transphobe doesn’t believe me.

I’m thinking of telling them how much better it feel to socialize with others girls than it does with males. However I’m worried that transphobes will still not accept my argument.

Is there a better argument to this?

edit I’d like to add that this transphobic argument is rotting my brain with anxiety. Your answers are really helping me with my mental health as it calm this anxiety. Thanks pals ༼ つ ◕_◕ ༽つ
