Have you ever had gluten free pastry?

Yes, I've had gluten-free pastries before. My friend has Celiac and can't consume gluten due to possible intestinal damage.

He has taken me to delicious gluten-free bakeries to get ice cream cookie sandwiches, pumpkin bread, brownies, garlic parmesan bread, quiche, meat handpies, etc

Just because you had bad ones doesn't mean they are all bad. Same goes with other food.

I mean you can choose to power through it. I'd sooner have a windy, achy gut than eat a gluten-free yum yum.

Well, if you had celiac disease, good luck living with permanent damage to your intestinal villi.
