Jean-Marie Le Pen is a right-wing French politician who has no business being in politics. No one should vote for someone who makes racist comments against one class of people or another. Le Pen shouldn't necessarily be banned, but his voting bloc should turn against him for such shameful behavior in a public setting.
No, this person should not be banned from politics for simply voicing their opinions about a certain topic. If they can still get the popular vote from the people, then they deserve to hold the office. If the citizens care about what they said then they will not vote for them.
Jean-Marie Le Pen should not be banned from European politics altogether for making racist comments against the Roma people. The history of the Roma in Europe is a hot-button issue. The problems with theft and other crime done by the Roma is a cause for the concern of many Europeans. This politician, although wrong for making a racist statement, is simply venting his frustration over the wrongdoings of the Roma.
It honestly depends on the remarks. There is a serious difference between making an off the cuff comment and actually espousing serious racist beliefs, and many of the comments on the Roma themselves come from people who have genuine reason to be frustrated with them in their countries and daily lives.
No, Jean-Marie Le Pen should not be banned from European politics all together for making racist comments about the Roma people, because nobody should be completely banned from politics for peacefully stating their opinion. It is true that Le Pen has some outlandish theories, particularly about women, but he can share as part of the political discourse without jeopardizing his standing.
