Disagreeing with the 'politeness' assessment of some of these words... type in 'Howdy' and the only "polite" words are "Welcome" and "Goodbye". More troubling

Disagreeing with the 'politeness' assessment of some of these words... type in 'Howdy' and the only "polite" words are "Welcome" and "Goodbye". More troubling to me is that this feels more like one person trying to impose their definition of "polite" onto others, and many of the suggestions seem result in speech that is weak, weasel-y, or lacking a feeling of weight.
