If you have a controversial or unpopular opinion, and you say or write it, sooner or later, someone is going to accuse you of "generalizing", as if this were somehow a refutation of what you have said.
It's pointless to argue with them. Debates are won, in the long term, by action, not words. But it helps us to understand why people would say such a thing.
Some people think generalizations are not "true", or, at least, not "true" enough. And yet everything we ever say is a generalization, whether it is that objects on earth fall at 9.8 m/s2 , or that women are shorter than men, or that I weigh 210 pounds.
So what does it mean to be "true"? What does the word truth mean? To say "accuracy" or "representation" means nothing, these are just other words for truth. The question to ask is why we care about truth. Why do we argue about what is true? Why do we seek to find it out? When we ask this question, we would in danger of disappearing up our own ass... except that there is a simple straightforward answer.
We care about what is true because it enables us to predict what will happen. Knowing the law of gravity lets me predict the orbit of planets, knowing someone's address lets us predict where we will find them.
Simple enough, and so much for philosophy. The word "truth" means "predictive power". This is how we test truth, and why we care about it, so this is how we define it.
Whenever someone asks you if something is true, ask yourself what it empowers you to predict, and what that empowers you to do. You do not need to possess the absolute truth, the perfect model that would allow you to predict everything, to say something is "true". It is enough that something be true enough to help you.
Are ALL women like "that"?
Who can say? To perfectly describe all women would require more words than can be printed on every flat surface in the universe, in microscopic print. We're not here to perfectly describe women, or ourselves, or humans in general. We're here to describe them well enough to get done what we need and want to get done.
Red Pill "truths" are not absolutely true, because nothing we have is. They are true enough to help us do what we need to.
