I am not going to address the controversy over immigration policy, though conservatives need to keep in mind that George W. Bush and John McCain (along with 23 other Republicans, as Obama mentions) supported this brand of immigration reform. What I will address is this partisan lack of respect for the President.
I will state that liberals are not exempt from this issue, as the decapitated head of George W. Bush was recently used in an episode of Game of Thrones. That definitely showed a blatant disregard for the office of the President. Bush may not be in office anymore, and I may have despised him as President, but that display was violent and sick. There was no excuse for it.
Likewise, this heckling “reporter” showed a lack of respect for a sitting President making a speech. Regardless of how they may feel about immigration reform, conservatives must ask themselves how they would have felt about a liberal reporter treating Bush with such disrespect. Those on both sides need to step up and admit it when one of their own acts inappropriately.
Attacking, interrupting, using violent depictions of our leaders, and in general showing a lack of respect for the office of President is wrong regardless of who does it. We need more civility in our public discourse.
