I have a good counter argument against modern liberal feminism, which is that Japan's sexlessness is because of excessive feminism, and the West is taking the same path. Japan was traditionally a feminist country, but the US occupation of Japan pushed feminism to an already feminist country, and boys gave up on women and love. Otakus were born. Incels are equivalent of the first generation otakus, and if Westerners don't take an immediate measure, most Westerners will be 40 years old virgin just like many Japanese are now. This theory is new, and I believe it helps when you argue against liberal feminists. Here is the intro.

People in the West have started to notice about Japan's sexlessness problem, but they don't think it is because of excessive feminism. Westerners have an idea that Japan is a country of misogyny and patriarchy and 100 years behind the West in terms of feminism, and it's difficult for them to think Japan is having excessive feminism. It is, however, a great myth. When the middle age Christian missionaries came to Japan for the first time, they were surprised how feminist country Japan was. Japanese are feminists in their own way. They just have different culture from the West. The history of the West is history of war, and women in the West used to be war trophies. Western women of middle age didn't have as much freedom as Japanese women had. I think the Western women of middle age were oppressed, but I also think modern liberal feminism is going wrong way, and I can say for sure that the West is taking the same path as Japan's. Japanese people stopped having sex in the last 30 years and are on the way to destruction.
