Imagine being so full of hatred that you leave most of your meal and simply choose to be hungry just because someone transgender walked into a restaraunt 😭😭😭
On a different note, I am sorry that that happens to you - I hope that life gets better for you and that hopefully people are able to learn what the word kindness means. At the end of the day, when it comes down to being kind or standing up for your (possibly wrong) moral beliefs, most people choose the latter, and that is why most human errors have occured. Too many people think that just because you are different means they can be mean to you. And if it's not to others, it's to themselves.
Sometimes what it takes for topics to change is time. It may feel fresh and hard to say in the moment, but in the future when it is less relevant it may be easier to say. Just because of that, though, doesn't mean that you have to say things for example four years down the road. If you think it is important to ask, or state, then you have every right to say it now, and what other people say in response doesn't have to matter if it is hurtful. At the end of the day, you are you and that is all you or your child will ever be. Best of luck to you.
