I needed to look it up too. I recognized Red and Blue Pills, but this is the first I had heard Black Pills.
Ass Hat is using incel(involuntarily celibate) terminology. The incels are a mostly online community of men who have trouble attracting a woman, because they have nothing to offer. They have bad financial prospects, terrible personalities, creepy look/vibe, etc. They talk online about getting revenge on women in general, and men who are not failures.
They have adopted a plot point from The Matrix series. If you take the Blue Pill in the Matrix, you remain in the dream world. If you take the Red Pill, you learn the truth, with all its ugliness. They claim they have taken the Red Pill, and learned to hate women, and men who are successful with women.
Now we get to the Black Pill. The Black Pill means that Ass Hat has learned the "truth", but has given up fighting the "truth", and has accepted failure. Whereas when someone takes the Red Pill, they learn the "truth", and then assumably use that knowledge to fight for what is "right".
On one level, it is good that he is saying he will not turn to terrorism, it is sad that he believes he lives in a universe where terrorism is the reasonable reaction to his romantic prospects. Somehow I think the solution is to get a better personality, speak nicely to women(all women, not just those you want to have sex with), and maybe set the bar a little lower as far as looks.
