You may not like what he says, but in America we have the freedom of speech. You are banning him from your platforms which you describe as:

Twitter-

"We believe real change starts with conversation. Here, your voice matters. Come as you are and together we’ll do what’s right (not what’s easy) to serve the public conversation."

Facebook-

"Our products empower more than 3 billion people around the world to share ideas, offer support and make a difference."

You are taking away the ability to have conversations, share ideas, and make a difference. You are NOT "doing what is right" rather you are doing what is easy, not to serve the community, but to serve an agenda. 

You have numerous people on your platforms who have said and done much worse, yet they have never been banned. You are playing politics, and need to stop and unban Donald Trump from your platforms. Americans CAN think for themselves to figure out what is right or wrong. We do not need you to "protect" us from words on a screen. We where all taught as children that sticks and stones....

Both of you are abusing your power. Both of you are playing politics. Both of you are in charge of social networks, NOT in charge of us and our ability to think. 

Unban Donald Trump, and stop abusing your power.
