my thoughts on spelling are that when someone is making an argument, their ability to use a word correctly is a necessary part of conveying their ideas clearly. and spelling a word correctly is a necessary part of using a word, since the spelling evokes the entire history of the word itself: the language and context it came from, the people, time and place that word originated.
i truly am interested in hearing your input on why you think it's important to use casing. change my mind
Sentences are one of the most important tools in language to organize ideas. A dot is too small and discrete to set apart sentences. Adding a dot ~and~ an uppercase letter right next to it makes a much better separator.
You're welcome to disagree. Since you were generous contributing about spelling - I'm not a native English speaker, btw -, I just wanted to pay back with a suggestion about text structuring and readability.

Kind of depends what the actions are: “Leaving your turn signal on after you have completed a lane change maneuver” and “carrying out a genocide” are both actions one might disagree with.
