There's no magic numbers where you "draw the line", simply biology. If a foid is capable of producing offspring, nature is telling her that she is ready. Purpose of sex is reproducing, if you have sex with a foid capable of reproduction then it couldn't be considered a crime because of some made up number by any sane person since it's completely natural.
Humans aren't robots with scripts like:
> if value <foid> [age] = <16 years then <attraction> = null
All the laws around the world reflected this. In US it was 12 or less in many places, according to catholic law it was 12 for foids, 14 for men, in the arab world, it was considered at puberty, in Europe it was anywhere from 12-15. That is without saying that they weren't really even properly enforced and many poor people didn't even know their age.
Feminists raised it fairly recently. The og feminists from the UK social purity movement raised it to 16 and 18 and american feminists followed suit, the rest is history.
Still plaguing even the minds of self-proclaimed blackpilled individuals. Blackpill = embracing biological realities no matter how uncomfortable they could be.
We should also remember that different races begin puberty at different times. Generalizing niggers at 9-10, whites at 11-12, asians at 12-13.
To find out if you are an agecuck, ask yourself the following:
Do i call for the deaths of men who are attracted to pubescent or postpubescent females?
Do i believe in generalized magic numbers instead of biology?
Do i believe that sex with a pubescent or postpubescent individual is automatically rape if it's below a magic man-made number?
I hope you agecucks also realize that your ancestors were not agecucks, if you call for the death of men who engage in reproduction, you are also calling for your own distant great grandparent's deaths.
Another aspect of agecuckism is the belief in agegaps. "A 14 year old is allowed to have sex with a 14 year old but not with 24 year old" or "someone shouldn't date anyone 5 years younger than himself". This comes also with the unfounded belief in magic numbers.
If all passports and IDs were burned to ashes overnight, you agecucks would have nothing to go off of. Then you would have to go back to embracing the natural order and determine consent based on physical maturity.
Agecuckism put simply is the belief in magic numbers, therefore asking "what age or agegap do you draw the line at?" is already an agecuck question in itself.
