You've got part of it right. Science shows that females fall within a certain range -- but it also shows that trans women fall within that range. Assuming they don't without evidence is prejudice. You judge them before you know or understand them and their issues. That is the very definition of prejudice.

The science actually speaks in support of trans women on this.  If you bothered to read the article, it shows actual data to support this. If you read my other posts, then you saw the many links to scientific studies showing that what I have said is true. 

Science shows that the biggest physical differences between men and women are created and maintained by hormones. Without testosterone, you don't have male strength. 

I am sorry to be the one to break it to you, but the science disagrees with you on this one. It's why the Olympics allows trans women to compete with other women. It's why the NCAA and others have agreed. 

Them's the facts, however uncomfortable it makes you.
