The Dutch have a saying, “Je bent niet van suiker” which means “You’re not made of sugar.”
Rain here is a fact of life, similar to the UK or Vancouver, Orlando or the Amazon Rainforest. Everyone who uses a bike for transportation here has a good rain jacket. And to put things in perspective, the normal rain seen in the Netherlands is more of a light drizzle and it generally comes in fits and spurts as moist air is pushed inland from the ocean. If you can afford to wait an hour, the rain is probably stopped.
Also, getting to the airport with a bike in the Netherlands is fine! There are nice protected bicycle lanes, a nice parking garage, good connections to neighboring infrastructure and you can always bring your bike down to the train platform if you need to go a bit further. When you live in a country that prioritizes cycling infrastructure, taking a bike is the practical, cheapest, and often fastest way to reach your destination.
Now to end on a point of more agreement, I agree with you that the demonization of AC in much of Europe is silly. Nobody is upset that in Bangkok or Tokyo that every building has AC. For some reason a certain type of European just doesn’t want to adapt and they will fight tooth and nail to prevent others from utilizing their own economic means in order to stay comfortable in their own homes. My home has solar panels and during the summer they produce much more power than I can utilize at one given moment anyway so if I want to run my AC at 400W during the peak heatwave that should be of no concern to anyone.
English actually has the exact same saying "You're not made of sugar, you won't melt."
A lot of people in car dependent regions have forgotten that you can dress for the weather, and that people have been traveling in all sorts of weather for hundreds of thousands of years.
Also, I think some of it is that decent parts of North America are vulnerable to heavy thunderstorms with hail and possible tornadoes, which are very different from the drizzle that Vancouver and Seattle get.
