I made nothing up.<quoted text>
What makes you think lesbians dress like a man to "attract another lesbian?" You create an argument over something you made up??
If you read their own discriptions, that is "who they are". Or, asked on your terms, okay, why do they dress up masculine?
Anything you define in relational terms must also be understood in evolutionary terms and be congruent.
Your fear is causing you to miss the simple reality that genes/brain/body 'wiring' gets mixed up all the time. Even our hair color is a mix. Denying that that mix is sometimes faulty is just plain stupid.
