French language Q&A Forum

I am puzzled by "tout oppose le" in the following announcement.

À l’occasion des élections européennes, le 26 mai, deux philosophes sont têtes de liste. De l’accueil des réfugiés à la gestation pour autrui (GPA), tout oppose le Français François-Xavier Bellamy et le Belge Laurent de Sutter qui se lancent en politique sans rien renier de leurs convictions métaphysiques.

The first sentence is clear. The second sentence mentions (1) the questions of the refugees and surrogacy, and (2) Bellamy and de Sutter who are entering politics, etc. But I do not understand how "tout oppose le" links (1) and (2). Does it mean Bellamy and de Sutter are opposed to (1)? If so, what is the "le" doing there? I can't work out the meaning here. Any help would be much appreciated.
