It’s called Freedom of Speech.
It's also tasteless.
Indeed- you have the freedom to be tacky- and we have the freedom to call you on it.
As to your earlier question- Hillary may or may not have gotten wind of this before now- or if she did- may not have had a plausible reason to bring it to attention.
Remember- Obama didn’t put this on his site til after hillary was out of the race. The document has given focus to the questions that apparently have been in the background- now there’s a way to bring up the subject.
August in Denver may be hotter than imagined.
I suppose your personal idea of freedom of speech is that it is fine to sink to the lowest kind of speech,,,you might consider that it reflects very badly on you as a human being and makes others likely to dismiss your ideas. Get down in the ditch if you like,,exercise your freedom but don’t be surprised when others tell you that your speech is offensive and low.
