yeah it's fun to argue!!
who wants a boring everyone nodding in agreement forum?
also i'll eat my words here....love is important!!! the most important thing probably, because if there was no love and no-one cared about each other then there would be nothing for voldemort to destroy. voldemort attacks and tears apart families and brings grief and tries to make averyone as angry and cruel as he is because he has never known, understood or experienced love. So he tries to take it away from everyone else and make world as souless a place as he sees it through his eyes. he is essentially declaring war against not half-bloods or muggles but against love and happiness and all the things he has never known.
but it won't work cos love is the last hope of the desperate, it's what holds you together right to the very end, and the very thing you will die for. you can never kill the love people have for each other,voldemort can kill the people you love but he can never change or kill the way you love and remember someone. voldemort will fail because you can never kill love.
