This is going to get political, and I want to say up front that I am very much a supporter of equality.
I will agree in the past that women have not been equal to men, and in some developing continents like Africa and the Middle East there is still a huge gap in equality between men and women. However, for years now, women in Western democracies and developed nations have had equal rights to a man. There is not one law in the US that favours men over women. There are several laws and false precedents set that give women more power. The main one is that if a husband and a wife split, then almost always the woman will get the full care of the child. Statistics show that 50% of domestic abuse happens towards males, and about 70% of domestic abuse and child neglect is by women, yet the man is presumed by society to be the one who is in the wrong.
There are also plenty of cases where women can also make a false accusation of rape. Even if there is not enough evidence, then the man is presumed guilty. This is not how justice works. Both the accused and the defendant are innocent until proven guilty with evidence. This whole witch hunt mentality does not help at all and is hugely unjust. It is like labelling someone a terrorist because they are a Muslim. Even if a man is cleared of rape, either the woman confesses she made it up, or there is not enough evidence to prove rape, then the man is stuck with that stigma, it can ruin his life based on one false accusation.
The pay gap is also a myth. Women in the same jobs get paid the same money. There are other factors involved in that women and men typically have different aspirations in life. Some may want to start a family where a man is more career driven. Or a man is more likely to work the dangerous job on the oil field or fishing. In STEM jobs women are 2:1 more likely to get the job over a man. Not because the women are necessarily better or more qualified, it is because there are not enough women in STEM jobs. It is not that they cannot, they choose not to for whatever reason.
Modern feminism has no interest in equality. They have this perceived patriarchy where they believe men have privilege, yet it is mostly men who are homeless, and even those who are homeless are still working jobs, while women get help from the state and the homeless rate amongst women is much lower.
I do not believe in Trump, and I don't particularly believe in the policies of the people who promoted Brexit. However, it was the whole mentality that if your views differ on certain subjects like immigration and abortion. You disagree with something that the Social Justice Warriors have said then you will be labelled a racist or a feminist or both. People are so fed up with political correctness and being told what to think. Not everyone has the same viewpoints but that gives you no right to use violence and label them a racist. Voting Trump and Brexit was a protest vote. They have had enough of career politicians telling them what to do.
People say what is wrong with saying, women only. If the theatre said, whites only, there would have been an outcry. If it were men only, it would be called sexist and misogynistic. In this case, they are favouring women over men. Sure, it is only a showing to see Wonder Woman, big deal, but it sets a precedent that it is okay to treat people differently based on their gender.
