Why was Pope Francis doves of peace for Ukraine attacked by angry birds

What an Irony. From the time of Noah Doves have been a symbol of peace. Christianity, especially, adopted the dove as a religious symbol of peace. Remember the biblical story of the ark, in which a dove brought an olive branch to Noah, showing that dry land was near and the terrible flood would soon be over. So why was Pope Francis doves of peace for Ukraine that he released with two children at the Apostolic Palace in Vatican City last Sunday immediately were attacked by angry birds, losing feathers and being driven away as a huge crowd watched?. Thousands of Tweets and Facebook posts were launched on the angry birds, some used words like "demonic," "omen," and "apocalypse", but what really happened there?. Still a question to answer. Let me know what you think on the comment section readers..........
