This the most hilarious and inspired tweet from Omnishambles.  If you can’t see the image, here’s the text:

Hello everybody!  I’m new to this chat
And so, to begin with, I’d like to say that
It really is crazy, if you stop to think
How all of us guys hope that one day we’ll shrink.

Wait, what, you like growth? Sorry, that I’m not getting.
I’d sooner be shrunk in an intimate setting
Her one and her only, being her toy alone
That seems pretty optimal. Each to their own!

What’s that? You’re a female? Neato, I guess.
(I cower at the sight of the cruel giantess.)
How mighty you look when you rise up and then
Take revenge upon all of the scared tiny men!

Beg pardon? There’s women down there too, you say?
Oh. Sorry, I should have suspected you’re gay.
It’s just that in my mind, the women I meet
All want to smear little guys under their feet.

You’ve got to be joking – you’re not into vore?
Then what are you even signed up in here for?
Can you even prove that you’re really a chick?
I didn’t come here just to moisten your dick.

So– oh. Oh, you’ve blocked me. That’s terribly rude
But what do I care, ’cause you’re clearly a dude.
This place is a graveyard. By why must it be?
That there’s no-one as into the fetish as me?

The un-self-conscious entitlement of far too many size roleplayers that Ominshambles deservedly skewers here is very simple to remedy:  remember that your preferences are not universal, and everyone deserves to have their own desires accommodated and respected.  Always ask before presuming what people are into, and graciously desist when there is no explicitly-given consent to proceed.  If not everyone’s having a good time, what’s the point?
