True, but making that meme is taking the lives of the first responders, the passengers and the employees of the towers and making a joke out of it. Also, why are you defending this meme so much?
Dude, as a Christian, the Bible tells me to show grace and forgive. I do forgive, but it also tells me to call out what is wrong. There is comment bellow that says s/he is a Christian and they laughed at this and that everyone needs to stop harping on this meme. But also as a Christians we are called to lead those who do wrong to the love of Jesus Christ. Who knows, Jesus may be your Lord and Savior as well... but there is right and wrong in this world. And this is is very wrong, but there is also forgiveness. God loves you and died for you and in his grace you are forgiven.
