If the aoc were 13 then many/most of the blackmailed politicians/public figures would have been getting 12's and under instead, and it would be less stigmatised to go for 12 and under or for them to have sex than it is now. And more of these young females would be having sex at an even earlier age, with all and sundry men increasingly going for them. Also, you know the homosexual aoc would also be lowered because muh equality, so it would be a massive boon to chickenhawks. Male and female relations, already dogshit, would worsen further.
The public also have no appretite to lower the aoc, it would be career suicide to suggest it.
Moreover, it's "far-left intellectuals" who are the strongest supporters of aoc abolitionism. Not saying that makes it bad inherently but one has to be suspicious of anything coming from that milieu.
The only potential valid argument one could make is accelerationist in nature but I'm sceptical about that too. The cultural degredation may well outweigh whatever backlash there is.
