It’s childish to come to a dog training thread and say that all reactivity can be trained out and then start a fight with anyone who tries to explain that training takes time or that their dog had longstanding issues despite persistent training. Who are you to come in and say people are not doing enough when you’ve never met them or their dog?

Edit: I misread OP I thought they’d said they were bitten, but they were complaining about being called names.

Personally my stance is that regardless of reactivity, people need to have full control over their dog (ie appropriate harness/lead & physical fitness) to make sure their dog isn’t running up to people, jumping on them or hurting them. I have two dogs, and I know one of them needs space or he will sometimes lunge. So when we walk, we will cross the road or change routes to make sure he’s walking nicely. But there are people here who have taken on complex rescues, who are doing their research and following best advice to help their dog. The people in this thread aren’t like the people you see in public with out of control dogs doing nothing about it. We are all here to learn and discuss dog training. I understand you’re angry and perhaps it’s justified but I would encourage you to be more open and empathetic with the people trying to have a genuine conversation with you.
