There's a lot of misinformation about how women's bodies work floating around out there, but when the source of misinformation is another woman you have to wonder what planet or alternate universe she just beamed in from.
In case there's anyone out there has been pulling a Rip Van Winkle for the last half century or so a rape kit is an evidence gathering tool. Evidence is collected that hopefully will lead to finding the attacker and it's all in one place. It has absolutely nothing to do with abortion. Treatment may also include offering the morning after medication to prevent a possible pregnancy. That may be where the confusion comes from. And some folks seem to be really easy to confuse.
Texas has just passed some of the most stringent laws in the nation all in the best interests of the poor misguided female half citizens of the state of idiocy also known as Texas. Remember it was Louie Gohmert who told a mother who terminated her pregnancy because the fetus basically had no brain beyond a brain stem that she should have carried to term. "After all, doctors make mistakes."
I looked up anencephaly on the net. Wickipedia, complete with pictures. You cannot mistake this condition for anything else and believe me there's no treatment for it. And, FYI, I don't recommend researching birth defects just before going to bed. Not good, so not good. And that poor mother. Frankly it would have been all I could do not to deck the SOB and take the consequences.
