Something funny happened here. Something really, really funny. But you wouldn't notice it by reading the article.
Let's have a good look at the timeline.
We have an "openly lesbian" lawmaker - the first openly lesbian lawmaker - getting elected in Texas. Apparently, before that, she was bisexual.
Now, she's pansexual. The article bills this as "going even further".
You know what I call it? "Yet another lesbian discovered she actually quite likes men at times."
Now that is headline worthy, but Huffington Post doesn't touch that one with a ten foot pole. Hell, they don't even ask her, "So uh... are you sure this time? I mean, your sexual orientation has switched several times now in adulthood. Can we expect this one to last, or..?"
Nope. She just switched sexuality, and got lauded for it. No one bats an eye.
If I were the reporter on duty, I'd have asked her, "So, did Exodus International help you with this change?"
