Firstly, in many cultures, people were forced to write with the right time up till the 1970s.p (https://en.wikipedia.org/wiki/Bias_against_left-handed_peopl...)

Left-handedness is somewhat associated with mirror writing (https://pmc.ncbi.nlm.nih.gov/articles/PMC2117809/:
“Particularly when produced spontaneously, mirror writing is a highly heterogeneous phenomenon: the mirroring may range from as small an item as a single reversed letter, through numerous reversed letters but not words, to thousands of pages of mirrored script; the place in the word in which a mirror letter occurs is variable, and numerals may or may not be reversed too”

its still a very unnatural action to do when writing, compared to a backslash

Except for writing, for everything else requiring skill he used his left hand.
