While I do not know who left Susans or the context of that discussion, I think that some people who are overly sensitive may be in a bad situation about which we do not have sufficient information. Yes, the world is cruel and we need a certain amount of mental fortitude to survive, but sometimes some overly sensitive individuals reach out to a supportive group for the box of sugar and kittens. There are periods of adversity that some people go through during which support matters more than a dose of reality. Someone I know from a local crossdressers group attempted suicide after being rejected by family, losing her job, getting ridiculed by society, etc all on account of her gender transition, and finally getting a dose of someone else's reality at a website which was supposed to be a crossdressers support forum. It took a lot of people to support her thereafter, but she seems to be living a healthy life now. So let us be kind to people. We do not know what else they are dealing with in their lives.
Once again, I do not know about who is the specific person we are talking about who quit Susans, but we should not make someone already feeling helpless more desperate as a result of our comments.
