I'm not happy that she's dead, not being edgy how I don't feel a thing, nor am I saying people shouldn't grieve for her, but how is not caring about someone you have no personal connection is rude?
Is your definition of rude anything less than positive? Am I not entitled to express how I truly feel about someone in a non-hostile way without it being considered rude?
In this context, yes. It's retty much a memorial thread, which makes it the internet equivalent of a memorial, which is a place where you don't open your mouth unless it is to express your condolences with the grieving or give a statement in honour of the decased. I fully respect your lack of affection and I feel the same mostly because I never even knew her and it wasn't under a dramatic circumstance, but I didn't post my opinion up until now for that exact reason.
And it's more the way you worded it instead of what you said. It felt like you "weren't giving a shit", which is on quite another level of unaffectedness than "I understand everyone's grief but I can't feel anything because she never meant something to me", which already is in a grey area. Not a criticism, just a well meant tip.
