we should really get rid of the idea of the “friendzone”.

I think this article explains it fine, but to summarize:

it comes from an idea that men (especially ‘nice guys’) deserve sex from women for being in their proximity.

being friends with someone should be a good thing and not just the waiting zone for a relationship.
