UPDATE***** I stayed very civil the entire time I was commenting. Give all factual evidence. And by the end of it, I'm called a little shithead, a traitor because apparently I want Muslims to have Australia, (even if they did take Australia, wouldn't be the first time a race has done it), told never to have daughters and so on. All while the worst thing I said was that I was sorry the wilful igorance that burdens this world and stops us from progressing and she took that as me calling her ignorant. 
She was my grandma that I never really knew. And I'm I'm not sad at all to lose such an ignorant racist person 
I will keep on anon for now. 
The first photo included was shared by a family member on Facebook. This is one of many she posts daily. It is clear were she stands within this topic. Now on this app I love debating and saying what I feel. But on Facebook I am very to myself. Barely commenting on anything specially not something that could potentially cause conflict. But today was the day I gave in and said what I needed to say. I hope that she listens and can learn. But she does seem set in her ways.
Now the question-what do you guys feel about this. The photo and the response. What would you have done differently?
