I really don't think that "both sides are as bad as each other" in any way. There aren't people within the remain side vocally calling for personal attacks and treason indictments above and below the line in the national press, there aren't people within remain campaign are questioning the ability of a judge to make decisions because he's gay, there aren't remain supporters declaring their name as "Britain First, death to traitors" as they're charged in court with the murder of an MP, there aren't remain supporters standing before billboards of brown skinned people declaring enough is enough, etc, etc, etc.
Whilst there is no way that anyone can claim that all these opinions exist within all leave voters (I'm sure many are horrified), there is rich veins of these opinions throughout the leave campaign and the media supporting it that cannot be ignored and have no equivalent on the remain side.
