[Fuck it, this one's a quadfor]

If I wanted to destroy a civilisation the first thing I'd do is teach their women feminism to turn them against the men & lower birth rates

...

2/ Then I'd open the borders to hostile racial-religious aliens who I'd then teach are being oppressed by the majority.

...

3/ Then I would shit all over the civilisation's history, cultural norms & achievements so they felt bad about their history

...

4/ Then I'd teach their children that ackkkshully, these other civilisations invented this stuff, not your civilisation, ie Muslims/Math etc

...

5/ Then I'd get control of their cultural engine I'd paint their men as the worlds most evil oppressors responsible for all bad in the world

...

6/ Then I'd teach them that any semblance of self preservation instinct was the world's most evil sin, ie. - racism

...

7/ If I got REALLY bold I'd start telling them their very existence in the lands their ancestors built gave them "white privilege", LOL!

...

8/ If they bought that little package of bullshit I'd go hog fucking wild and just throw the borders completely open

...

9/ Eventually when they were a minority the gloves would come way off, I'd use my armies of third worlds against them relentlessly.

...

10/ Laws would go from "hate speech" (to silence them) to laws forbidding them from even having children or owning property

...

11/ Hell, they believed my "white privilege" lie, what can they do as minority now? I'd be my greatest victory since South Africa.

...

12/ I'd also promote every kind of degenerate behaviour possible too, from bizarre sex stuff to outright mental illness. Forgot that one!
