Im tired of seeing all the 'gender is a social construct' plastered everywhere. They dont even seem to understand what gender even is. They think gender is clothing, expression and/or roles. It is biological, nothing what so ever to do with society

What are some good studies/evidence I can link to as backup? I know about David Reimer's case which I use, I've heard a few other things like a cis woman wearing a prosthetic penis and would break down over it, even when she knew it would be removed. Any other things I can link to? I always try to educate, fight ignorance and bigotry whenever I can. Im tired of misinformation being spread as truth which can be as bad from trans people as cis people

There's a handy collection of links in this article:

Although it's now quite an old book, for an understanding of the basic biology of how the sex-specific differences between the brains of men and women arise (and how those differences influence adult behaviour, preferences etc), "Brain Sex" is difficult to beat:

This paper:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3146061/

provides a good overview of the history behind the discovery that it's hormones produced in the testicles (primarily testosterone and DHT) that drive male brain development, and how there's an abundance of research in a range of animal species showing that administering external testosterone can cause male brain development in genetic females.

You could also point to some of the videos on youtube of CAIS women, who, although they're genetically male and have internal testicles in place of ovaries, have developed as female instead of male. They have a mutation to their gene for the androgen receptor, which has rendered their bodies completely insensitive to testosterone, so all their development takes place as if there's no testosterone present.

Here's a great page about Androgen Insensitivity Syndrome, and how it completely demolishes the argument that your sex is determined by whether you have a Y chromosome or not:

Hopefully that helps!
