I'm definitely a grinch, Christmas is repulsive to me in most respects. I see religion, tradition, obliged gift giving, obliged kindness, mindless zombies calling out "merry christmas", lies to children, threats to children (better be good, or else...), christmas songs irritate me and seem to get worse every year. Business takes advantage of the mass hysteria and laughs all the way to the bank.
I'm not a mean grinch though, if someone wishes me a merry christmas I'll be like, "yeah great buddy" and give them a thumbs up. But is it not more virtuous to be kind because that is who you are? Or to give a gift because you really do care, instead of a calendar prompt? I find that my random gifts and acts of kindness are much more appreciated.
