I have kids and I don’t mind people saying “I can’t stand kids.”
You have to understand for them to say/think this, probably they were at some theater, restaurant, etc…where the kids there also were very poorly behaved. People are made up of their experiences and it’s taboo to have any prejudices nowadays.
If you choose to ignore people who have some, feel perfectly ahead. That’s your choice. It shouldn’t be used in some unlawful actions like hiring, housing, etc since that’s illegal, but I think everyone is racist/prejudice to some degree that it will affect all decisions a little.
I agree that society doesn’t allow freedom of thought. You say anything like “I hate dogs!” and people think you are the like the equivalent of being Hitler…(maybe I got bitten or mauled?)
I think people just need to be more tolerant and accept that some people aren’t like us and it’s ok for others to ignore other people or have prejudices.
