I don't think they're as small as you're saying. There have been multiple well documented incidents with 737 MAX that have not been with the A320. Maybe you think it's small enough to not worry about, said incidents are enough for me to want to avoid that aircraft entirely. Absolute risk is certainly still low, but I'll take the safer in comparative risk any day there.

Paying attention to planes and risks of other forms of transport are not mutually exclusive.
