The issue isn't so much with Dilbert as the context Dilbert is in. Let me try to explain this. The sarcastic "I am X identifying as Y" joke is a good example.

The issue isn't so much with Dilbert as the context Dilbert is in. Let me try to explain this. The sarcastic "I am X identifying as Y" joke is a good example. The structure of the joke is Y is something no one will seriously identify as. This means "X = Black, Y = White" pattern matches. For the LGBT "context", the common usage of sarcastic "I am X identifying as Y" translates to "I don't think transgender identities are valid". The Non-LGBT context doesn't assign a specific meaning to the phrase. This sets up a scenario where one group has a rule saying "X -> Y" and another has "X -> ?". And here's where the problem comes in. Comic strips have limited bandwidth and they rely on context to be understood. So when Dilbert says "I am Black identifying as White", the LGBT context immediately translates this to Y, wherewas the Non-LGBT context does a page fault and looks elsewhere for what it could mean. In isolation, this looks like LGBT people are being overly sensitive, but every human is "overly sensitive" in some way. We all operate in our own context based on what we've experienced.
