I wonder if one of the transphobic questions was 'if you are a man does that mean you have a male body?'
These are some of the questions from Venice Allan's twitter thread that I think this person might have found transphobic, because they are likely to have taken them as a personal attack.
What is gender and how can it be mismatched with a person's sex?
What is the moral case for inducing an addiction to plastic surgery in ppl who have noted co-morbid conditions often including obsessive thoughts and behaviours?
If being transgender is not an illness, why should they be offered radical surgeries and powerful, life changing drugs?
How can doctors justify prescribing high doses of testosterone to girls and women when much lower rates of naturally produced testosterone within the female body is a key indicator of harmful health conditions?
Why does anyone need cosmetic surgery to be happy with their healthy body?
Anything that makes them think about what they have done to their body and whether their medical treatment was the right thing to do is described as transphobic. Once you have done irreversible things to your body, it must be quite distressing to hear people saying that maybe this isn't the right treatment for someone in your position and perhaps we should be more cautious in future.
