With most markdown renderers you need to use ¯\\\_ (ツ)_/¯, first to escape the \ and then to escape the _ so it doesn't think you want italics with _ (ツ)_, but looks like Lemmy's is fine with ¯\\_ (ツ)\_/¯, go figure ¯\_ (ツ)_/¯
Because you will suffer and then you will be corrupted by the demon of shortcutting and never really understanding anything. Yes, embrace the evil! Or resist the temptation and train your spirit (nothing trains the spirit better than abstract infinite vector spaces).
