To address the OP - no it is obviously not a crime to say that women don't have penises.
I have stated on previous threads that one of the joys of university is the fact that day-to-day responsibilities which take up the time of the rest of us, are largely taken care of, leaving superior intelligences fa too much time to get het up about things which are really not important enough to receive the levels of time and attention that they receive - and this is another prime example.
Out here in the real world, we don't have time to analyse and ponder the imagined deeper meanings in simple everyday pronouncements, if we did, to the level that these students do, the world would grind to a halt.
Therefore, we take standard statements at face value, and move on to more important things.
I'll give you an example - if I type the phrase 'The world is round', then everyone knows exactly what I mean.
If you were a science student, with the free time and lack of anything important to do with it, to analyse my statement, you would argue that the world is not, in fact, 'round' and you would be absolutely correct - the world is not 'round' at all, it is an ellipse.
But honestly - who has the time, and more importantly, who really cares?
So if a man states that women do not have penises, then the majority of people know exactly what he means by that.
If you are a trans-sexual, and you want to be hyper-sensitive, and make an issue, you would need the time, and the thinking ability to do so - you'd need to be a student!!!!
And there we have it.
Personally, as someone well past student age, I would suggest that any gay or transsexual person would be better advised to use their time to assess and deal with the very real and serious issues that their situation forces on in them while they live in a heterosexually dominated society.
And I would also suggest that part of that adjustment, and living a life, would include knowing when genuine damage and offence is intended, and when it is not, and the sense to work out the difference, and react accordingly.
