Is this parody? Honestly I can't tell.
It's amazing the conclusions you can come to when you filter everything you see through the lens of feminism.
1. Airplanes are uncomfortable for everybody. They design the seats in a way that allows them to pack in as many people as possible, and make as much profit as possible per flight. It has absolutely nothing to do with gender.
2. What a shining example of a first-world problem. "I feel uncomfortable on airplanes". You're experiencing the miracle of flight. You're able to travel distances that would have previously taken weeks, in mere hours.
Did you invent air travel? Do you have the slightest idea of how a plane flies in the sky? You're one of the most privileged people that have ever walked the earth, yet you're simultaneously complaining about being oppressed. It's actually fascinating psychologically.
