According to TRP theory, the reason women move on so easily from a relationship is the war bride dynamic. This means that that when a male of another tribe kills a woman's husband and takes the woman prisoner she is very likely to develop a kind of Stockholm syndrome and follow the new man instead. Far-fetched? Maybe, but apparently this behavior is common in some animals too. This guy analyses at around 44:00:

However, if war rape was really so common that it literally changed women's phyche at an evolutionary level then I think it's safe to assume that men have natural urges to rape and will do it under some circumstances.

Men here say they would never rape. Oh really, so if you were part of the Red Army in the 1940s and war rape was not only accepted but actually encouraged, can you say with 100% certainty that you wouldn't do it? You can't say it because you have never been in a similar situation. I personally think that 99% of men would be rapists in this scenario. War rape is indeed very common if you look at history.

Therefore, men shouldn't be offended when radfems talk about rape because it is true. You can't look at the ugly side of female nature while ignoring the ugly side of male nature.
