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.
Well OK. But we all have to get along together on this earth and being intolerant of our fellow man's sexual preferences and appetites doesn't help this.
