The question itself is not offensive, and the idea of the filtering is perfectly valid. The problem arises in that the level of risk being filtered by "sex with another man, ever" or even "sex with another man, last five years" is much less than other risk factors that are more common but not screened---but the presence of the question (and absence of others) has the effect of spreading FUD about the risk factors, and thus has the effect of spreading and reinforcing homophobia even if we generously assume that homophobia is not the reason for the rule in the first place. Reducing the time limit and/or adding other factors to the screening would remove the objections of (most of) the people that complain about this rule.
