You seem awfully sensitive for someone who cheerfully said all of this to anyone who said they sent cards to their children, even if they explained their entirely innocent family tradition :
"It's weird and creepy for parents & children to exchange Valentine's cards."
"Parents shouldn't be sending expressions of romantic/sexual love to their own children."
" disturbing and creepy "
"Well... yes? I thought that was completely clear from my posts." (In response for someone asking you if you thought it had incestuous overtones)
"It may be 'just a bloody card' but it's a card that comes from a tradition of sending cards to people you want to fuck."
"Yes, a parent sending a child a Valentine's card has unpleasant, incestuous, sexual implications. "
"OP is right to be creeped out and disturbed."
"Valentine's cards are sent to people that you want to fuck." (You were so proud of it you said that one twice)
I feel that my summing up of your insinuation was fair, and my 'personal attack' (about you not realising that things had moved on? Really?) rather pales against your own comments above.
