I don’t often bold comments, but i do like using italics and sometimes all caps to EMPHASIZE an important part. I guess the difference for me is whether it’s something I get fired up over like bodily autonomy. I use caps to emphasize more than italics.

In a regular discussion or if I’m just overexplaining something, I stick to italics. (and if I feel something needs additional clarification, but also maybe the reader wants to skip because it’s not really necessary, I’ll use parenthesis to show where you can skip to)
