There are videos everywhere of them saying "one mans sperm can impregnate multiple women and repopulate the world". They then record some young random lady and try to get her to argue back and she can't. However, their argument about sperm actually does the opposite of what they intend.

If one mans sperm can repopulate the world, then if the male population decreases society will continue to move on like nothing as long as that those few men still produce sperm. But since it takes 9 months to make a baby, if the female population decreases society is doomed no matter how many males their are in the population. Their argument to try to put women down actually ends up back firing on them. Especially since sperm backs exist.

So why do they keep using it to decrease a womens value when it actually decreases their own value since sperm is so powerful and easily replaceable?
