Mildly Interesting

Its a statistical effect, not infantilization. Suppose they are just lazy. What then? Do you expect that if enough people realize this and call them out on it, that people that didnt vote will suddenly realize the error of their ways and go do it next time? If they are, but you treat them as if any existing difficulty to voting was the cause and work to make it easier instead of casting blame, what harm would be done? If I "stop infantilizing lazy voters" as you think it, what benefit is achieved?

It seems to me that if what is necessary to achieve a better outcome is for people that tend to stay home to vote instead, then it makes sense to do whatever it is that will make them more likely to do it, whether or not they seem to deserve it or not. And people rarely do what you wish them to do after you assign blame to them for something, regardless of how true that blame is. Assigning blame, if you can back it up with appropriate consequences, can help change the behavior of specific individuals. But it virtually never is effective at changing large and vague groups whose members you do not even know. To do that, you have to create systems that push people into a desirable behavior rather than leaving it up to their personal responsibility that has already shown, by the fact that the end you want isnt already happening, to be ineffective.
