we're not downplaying anything.

Dude if I post a meme about pinochet, adoplh shitler or suharto on a misantrhopy forum with my joke being 'iF yOu WaNt ThErE To Be LeSs HuManS!? I HavE JuSt thE MaN fOr THe jOb!!1?1?1?111¿' do you think the people on that there forum would laugh in unison with me or ask me to leave forever?

That is exactly what this meme is doing.

Being childfree doesnt mean 'Give a pass to ALLL humans who shown cruelty to children' instead it means 'Give a pass to ALL humans who choose to live a peaceful lifestyle where they choose to exclude themselves from things involving children.' ...Thats it

Same can be said for things related to misanthropy . Misanthropy doesnt mean 'Super-Individualistic-Turbo-Genocidal Hatred Of All Humans!!!1!1!¿ Give a pass to ALL HUMANS who have done cruel things to reduce the human population !1!1!32¿¡' instead it means 'Give a pass to ALL HUMANS who have peacefully chosen to exclude themselves from other activities involving other humans.' ...Thats it.

We shall neveer give a pass to a hellish demon like casey anthony who will probably become a serial k1ller
