Yes you do. Everyone and everything is deserving of respect at all times, especially the ones/things you disagree with, or dislike. The same is of every thing from animals to material objects, lest they wantonly waste and/or damage stuff.
This is why _every_ democracy in the world demands their politicians act with respect to their opposition. Some honor these rules more than others, yes, before you quote some breakdown of the process somewhere.
Which renders the rest of your post pointless nonsense.
