Great idea!! Let's think of all the reasons it could hurt someone's feelings.
But here's an interesting fact about being offended: it's a choice, just like most emotional responses.
You can choose not to be offended. That doesn't mean you always should choose that path but most of the time it is the better choice.
If someone cuts you off in traffic on the way to work, you can A) be mad at the person, try to retaliate, and go to work in a bad mood or you can B) forget about it and not waste your emotional energy on a bad driver you will probably never meet.
Choosing to not be offended is a prerogative of the privileged. You might get to choose not to be offended but that's likely because you're not the target here.
Consider two things:
1. You're saying that someone doesn't have to be offended when that person's entire identity is being lampooned. Sure, I don't have to be offended if someone makes lazy Mexican jokes... but that doesn't mean that their behavior isn't reprehensible, not funny, and contributes to a culture of hatred and violence.
2. Considering that a culture that treats cross-dressing and transgendered people as "humorous" leads pretty quickly to making those people targets of scorn and violence leaves some of the choice out of it, don't you think? A transgendered person might "choose" not to be offended, but then a potential attacker might "choose" to think of someone as less of a person... and images and words like this contribute to that.
It sure seems like you're comparing a culture of derision and violence against transgendered people to getting cut off in traffic.
An individual's specific, isolated behaviour is distinct from an individual's general, systematic behaviour. Somebody cutting me off in traffic (because they're stressed, or late, or sad, or angry, or for whatever other reason) is massively different from somebody cutting me off in traffic because I'm transgender, E.g.
I accept that this is an awful particular example, but I'm working with the framework you've offered, and I trust it gets the point across.

Choosing to be or not be offended is similar.
