AITAH for not caring about excuses when you don't clear snow?

I live in a wonderfully walkable community, which I love dearly for that reason. This past week, we were hit with quite a bit of snow and follow on days of sub freezing temps. This has resulted in any sidewalks that weren't cleared, becoming huge patches of ice. As a currently pregnant woman, who walks my small child to their childcare, this frustrates me to no end. In a local group, someone shared a photo of an unshoveled icy sidewalk and kindly asked for people to do their civic duty. By God. You would have thought that she had asked them to do something unreasonable. People freaked, and I responded saying it's the homeowners responsibility and if they physically can't, they need to hire someone. I have been vilified by members of the group who insist that as a community, we need to just do it for them unprompted. I see this as total bullshit. I helped with shared sidewalks, we cleared our stuff,, but i am not going around to do everyone's sidewalk when you can't even say you have a problem. They are supposed to give fines, and I'm sick of it. So, for my attitude towards this, AITAH?
