From time to time, you will have one person - springing out of nowhere to dismiss women's pain and struggles.

Like this guy who put a picture of his scraped knees and said that he doesn't want to hear about period pain until women go through such injuries.

Two points to make here:

1. How does he know how much period cramps hurt?

2. Why did he assume we have never got our knees scraped?

Anyhow, people on Twitter put him in place soon with sarcastic remarks and some biology lessons that he seems to have missed in school.

Oh, there's one more question I came across - from which knee is he going to give birth?
