You can't be calm and rational if you've ever used the nickname "Crooked Hillary" in a post that you might otherwise consider serious.
Yes. Constructive criticism of a candidate is one thing. Restoring to chep and lame stuff like this makes your entire argument useless.
Why? She is crooked. There is no doubt about it.
The people using that term are just telling it like it is, without PC filter.
Being anti-PC isn't an excuse to resort to elementary school-level insults while trying to win a debate, nor is it an excuse to insult anyone you want any time you want.
