I said "kind of", not "is". In principle this kind of argument can be done in an intellectually consistent way, with sources and statistics.

Instead you've followed a pattern I've seen time and time again.

An uncontentious fact (men are more visually aroused) followed by a unsupported train of thought that leads to a significantly speculative conclusion about the preferences/desires of a demographic that to some degree we find distasteful as a society.

If you evidence for your final claim I wouldn't have a problem, its just that this kind of discourse more often seems to pass bigotry off under the guise of just "speculation".
