Whilst I agree that people should be treated with decency, you can't just ignore hard science. A biological man is still a man, regardless of treatment: The wound never heals and constantly requires medical attention. Forced speech is a dangerous path to take, particularly when the topic is based on weak social-science as the argumentative standpoint.

There is very little, or at least weak evidence to suggest that misgendering someone actually negatively impacts their life, or that society itself does. Even if a person is impacted positively by society their suicide rate stays the same, of which is 40% of the transgender population. That is a very sad, and crazy statistic. This also applies to the population regardless of if they are pre-op or post-op. The issue itself is more-so correlated to internal thought processes and thus to the 'self'. Therefore, it is a psychological issue.

Hard science should not be disregarded in favour of someone's feelings. The issue is multifaceted and needs to be analysed with care, and without bias. Rather, it should be looked at from an objective standpoint, with empirical data, facts and logic. Doing this will help find a solution to their suicidality over representation.
