Don't agree with the phases here, those are kind of radical. It would not serve us evolutionarily to be pansexual, or even homosexual (no offence intended). It is nice that we're becoming more tolerant, that's an improvement.
What's needed is not more tolerance, but more INtolerance of ignorance and superstition. More assertion of self-evident scientific truth.
So what you are saying then is people should only tolerate yourself and people who share your ideals and any one else should be treated with intolerance? Of course you personally could never be capable of ignorance, and you are superior to everyone else right?
True science is rarely "self-evident", that's why they have to do these things called experiments to test out various theories of science in order to find the most efficient solution to any particular problem. The result of this process is that there are always many opinions on any given scientific subject, and this is by design. Intolerance of opposing viewpoints is unscientific. You however treat science as if it is a religion with "self-evident truths", but I wouldn't expect any actual logic to seep out of the brain of a degenerate Marxist such as yourself. You have to learn how logic works first for that to happen.
