I could not find Explosive Stress Anger Disorder, but maybe it had a name change in recent years? This can happen. What I found was:
IED (Intermediate Explosive Disorder) isn't Trump Derangement Disorder.
Trump Derangement Syndrome is an old propaganda tool of the Republican Party. First known as Bush Derangement Syndrome and used again after the passing of Margret Thatcher in 2013 when it was deemed "inappropriate" for people to remember her legacy in a negative context a week or so after she died. In 2003, Charles Krauthammer defined the term Bush Derangement Syndrome as "the acute onset of paranoia in otherwise normal people in reaction to the policies, the presidency - nay, the very existence of George W. Bush."
Given there are few people nowadays that would compare Bush to Trump, not to mention how many have changed their stances on their issues with Bush's handling of Iraq, it should be in poor taste to invoke the same propaganda to waive the criticism of Bush's handling of the situation for Donald Trump in... well, really anything he does.
Perhaps you could argue that Trump received more negative than Bush, and that may be true. Despite the fact the left label him a conman, he doesn't do much to convince them that he's on their side and instead openly antagonizes their representatives while carefully not antagonizing his constituents themselves.
The same, however, cannot be said of his supporters. Who are not so much conservative but rather anti-liberal.
It appears that most of the people who enjoy the anonymity of the internet and take full advantage of it seem to relish their online hatred no matter what their political affiliations. You could say, quite accurately, that they suffer from IED.
