They put up the displays to celebrate Pride Month. I would guess they would take them down at the end of Pride Month.

You came on the thread to talk about it. You asked "what is he trying to prove?" You call him a fucking moron. Sounds like you care and it angers you.
What is moronic about a transwoman trying on tuck-friendly swimwear? Would the friend you mentioned before who thinks his gender is changing be a moron if he went to Target and tried on a tuck-friendly swimsuit?
You should get him a Target gift card, to show your support.
The Target workers found it funny. Do you think they are transphobic?
Yes, you should try to get some fun out of life yourself.
Maybe this will help (Plano, Texas, of all places):
