We horn players certainly deserve to be dissed sometimes.

If we want to play with guitarists, though, we should be able to play in keys with lots of sharps!

John has a great point that a non-brass player may not know: with only three valves on most trumpets and other horns, one might think there is only one way to finger a given note, but some notes have alternate fingerings that are more in tune in some keys. And a famous trumpet player, Charlie Shavers, was reported to have said, "Anything above a high C is played Open.". I use standard fingering up to G over high C, and above that, I don't care because I will never go there in mixed company. Too much pain and swearing, and maybe a trip to the emergency room.
