Apparently it still needs to be said.
Rape jokes are not funny.
Some of you may agree wholeheartedly with that statement.
Some may be on the fence, leaving more room for context and execution, etc.
Some of you may think that all rape jokes ever are funny.
To be frank, this is your right. You are entitled to think any thing at all out there ever is funny. No government entity is going to break into your living room/ bedroom/ mother's basement and disappear you because you find rape jokes to be funny. Nor am I advocating that we change the laws so this can and will happen.
Nope, I do not at all intend to infringe upon your rights to independent thought and to find humour anywhere you like.
When you make rape jokes, I will think of you as a potential rapist. Or, I will assume that you are just not a safe person to be around and will not trust you any further than I can throw you. Because, if you're making rape jokes, or falling off your seat laughing at a rape joke, then I can only assume that you will not help me if I am or someone I love is being or have been sexually attacked, and I cannot trust you to not support the rapist.
If you are making or laughing at rape jokes, you are identifying with the rapist. You are agreeing that, "Heck, not only is rape not a big deal, but it's funny and something I can derrive pleasure out of at least in the form of humour."
I might not even let you know that this is what I'm thinking at the time. You might go on, giggle-snorting to yourself, completely and blissfully unawares that my stone silence and dead-eyed, slack-jawed response means that you've dropped from my "people I trust and look up to"-list to my "people I will avoid because they are not safe"-list.
It is physically safer for me to assume you're a potential rapist if you're giving me signals that you're a rapist or are ok with rapists. Because if you are a rapist or a rape apologist and I'm attacked, misplacing my trust in you could have serious and tangible consequences for me.
If you think that it is more offensive that I would mistrust someone and view them as a potential rapist because they made a rape joke than for someone to have made the rape joke, then you are not worth my trust, either.
