There are some wild sweeping generalisations in your posts OP. Not all "boomers" have the same shitty attitude that you seem to be implying.
There are plenty of self-serving and shitty Millennials too, as there are in every generation.
I'm not a boomer myself, but I do object to lazy tropes and those of the "ok, boomer" variety are pretty unpleasant.
Women of the boomer generation actually had a pretty shitty time in many ways. Women weren't allowed to get credit cards or a loan without a signature from their father. Women weren't even allowed to open a bank account without permission from a man until 1975. It took until 1990 for the law to allow married women to be taxed individually, and not as an extension of their husband.
Statutory maternity pay wasn't introduced until 1987 and wasn't made compulsory until 1993.
Until 1982 women could be refused service in a pub, simply because they were a woman.
And let's not even touch on the subject of rape and sexual assault. Marital rape didn't become illegal until 1992.
Lots gets written about how the current generations won't enjoy the same financial benefits as the boomer generation but there are plenty of things that are better today, especially for women. That's why it's lazy to cast aspersions on the boomer generation as it fails to consider the full range of circumstances that were present.
If you want to criticise someone, make it personal, don't suggest it's because of their age or generation. It's unfair and insulting.
