There are no girls on the internet, so I assume all posts are made by men.
Do you think only males make those assumptions?
A lot of women also make these assumptions too.
It is not fair to assume all people on the internet are male. There can be good reasons women would hide their identities to avoid harassment.
Don't be a pussy lmao.
As a woman I hide my identity some times to avoid harassment. Maybe you could pretend to be a woman for a day and see how men treat you online. It might be eye opening.
