It's actually quite popular to claim to be a WNBA fan, so it's rather going against the grain to claim otherwise. I believe you talk up the WNBA b/c it's what you're conditioned you need to do. I doubt most supposed WNBA fans are fans at all, but are just going along with the dictated narrative.
You still seem to cling to this notion that if you bring a topic up or discuss it then you must be a fan. I can freely talk about many things of which I have some knowledge/awareness but no personal great interest. As it pertains to the WNBA, I speak of it mostly as intersects with sociopolitical issues, which they thrive on. The WNBA thrusts itself into social issues, so I speak primarily to that aspect of it.
And occasionally I make fun of how stupid they look trying to play basketball.
The WNBA has realized that very few people are going to tune in to watch them fumble and bumble around a basketball court trying to actually play so they create drama on and off the court with social issues (especially racial triggers), fashion statements and cat fight feuds to gin up interest.
