    Ending: talking about sperm whales. On a Y chromosome video. Can’t be a
    coincidence LOL

    Reminds me of the book Children of Men. Where one day we wake up and find
    out that humans just can’t have babies anymore.

    Can you make a video about how sex is determined by more than chromosomes
    and sex is more of a spectrum than a dichotomy?

    why does it rain when you wash your car

    To be honest, if gender is not meant to describe the biological sex of a
    person, and is only used to describe the way a person looks or acts, it has
    literally no use in science.

  11. Sean Bush says:

    notice how he has to distinct biological genders because of you transgender

  12. Okami Films says:

    Next time someone says they are transgender, ask them if they have an X or
    Y Chromosome. That’ll shut them up.

    So what you’re saying here is that it’s not the size of the boat, but the
    motion of the ocean?

    Well, Feminists. You did it….you won.
    Men are going to be blinked out of existence, and soon we’ll all be winey
    crybaby egotistical back-stabbing spiteful little bitches.
    Are you happy?
    Are you happy to know that the future will be one where there will be
    constant war, if only because Madam China Empress Twittered trash about
    Miss USA President’s matching skirt and vest ensemble? Where scientific
    advancements will come to a virtual halt, because you can’t flirt with
    mother nature to make a breakthrough discovery?
    There will be a day when all the girls will sit around a table, pouty faces
    and cross armed, trying to figure out a way to re-invent the Y chromosome
    just so you can bring back real men who’ll swat at that spider crawling on
    your pillow, and fix that leaky pipe under your sink.

    This is a grave new world for men. A men being oppressed by women
    today…who’ll cease to exist tomorrow.
