You just need to remember that your speech can have consequences. You can speak alright, nobody is saying you can't but the things you speak can have effect on your social status and the way other people see you. So you can say whatever you want but based on what you say other people may and will judge you and you have to accept that. If you can't accept that then speak within your group of people who have similar views or live separately from other people. Or brainwash all other people to accept your view.
I agree cats shouldn't be let out roam freely like that anywhere and anytime but it's better cats than dogs. Cats in general are smaller and less aggressive to humans. Like how many large dogs you could find in 100 dogs and how many big cats you could find in same amount of cats?
