Predicting the future is your solid life advice? Would you recommend a crystal ball, a ouija board or a magic 8 ball?
Should I only concern myself with the long term history or do I have to worry about regressions mixed in? A lot of people thought they were on the right side of history with gay rights in Leninist Russia, it didn't turn out well.
FWIW my 'wrong side of history' comment was meant facetiously, nobody can know what the right side of history is until long after. Though in your specific case, I'd say they were, hopefully their day will come.
