With strangers? Probably not unless I'm passing a blunt.
Why not? Why the hesitancy?
I wouldn't hesitate to call a trans person a person, stranger, friend, acquaintance, buddy, or any number of gender neutral terms. If they're a trans man I wouldn't hesitate to call them dude.
But you, you use dude, you profess to believe that it's a gender neutral term. You wouldn't use it for a trans woman without hesitation? That something to introspect over. Same as you could possibly introspect why you believe dude is a gendered term in all cases, but conveniently not this one. Use dude how you like, just be honest about it.
I'm not reclaiming it. I'm encouraging non-males to use it because it's fun.
This you?
I stand by that dude is gender neutral if for no other reason than to reclaim it as such.
I'm not sure it's for men to reclaim gendered words or encourage non-men to reclaim specific words for my own usage. For the same reason for the same reason I don't think straight people should encourage queer folk to reclaim words to make me more comfortable about using them. Or non white folk should reclaim race words so I can use them. Can you see why?
