Sorry, then those particular rights groups (please name them, because they don't all do this) are using it wrong. Minority just means smaller numbers, hence terms like "minority rule" and "minority government" where a few people of a certain sort rule everybody. "America is governed mostly by a rich minority" is a valid statement, but not if people insist on using weird definitions of the word.
Women have not been disenfranchised in the USA for nearly 100 years. Disenfranchised means they cannot vote. People have agreed that words mean certain things. Using them to mean other things confuses everybody.
As for middle eastern countries having female leaders, the only ones that have are Israel and Turkey, considered the most developed and least sexist partly because of their Occidental influences (Ataturk made huge efforts to make Turkey more European, while Israel was founded by US and European Jews). As for North America, Canada has already had a female leader. Again, generalising is bad. Turkey and Israel are not the worst middle eastern states that people here are complaining about. They are likely thinking of states like Saudi Arabia which have certainly not had female leaders.
If you think a weedy man could get punched in the face by a female Olympic boxer and shake it off, you are daft. Generalisations are BAD. Please learn this. Men are stronger than women on average because they are bigger on average and do not give birth, so have more space for skeletal muscle. Their shoulders are also usually broader. These are only general rules, and a bigger woman will often be stronger than a smaller man.
