With a political party, you essentially have 3 options:  1) To tell the truth, be honest about what you believe in, and try and convince the electorate that your positions are the correct ones.  2) To lie. To say whatever it takes to get into power, and then once in power to blatantly back track and renege on all your pledges, and do what you initially intended to do anyway.  3) Opportunism. To eject your entire core ideology in pursuit of power. Like option 2, say whatever proves popular to get into power, but unlike in option 2, to continue doing whatever the media and opinion polls tell you will win votes whilst there. In order to keep yourself in power for the maximum time.   Which one are you advocating? I think telling the truth is of abosolute importance, but that does not mean you can't leave stuff out. Holocaust revisionism for instance, there is a place for it, but leave it to the brave historians who dare to make their  taboo  point. I fail to see any adavantage of a nationalist party speaking about it, but I see a lot of disadvantage.
