Well...not with the additional protocol to the European Convention on Human Rights on national minorities 

The Assembly considers that such a protocol could refer to the internationally recognised criteria laid down in the Copenhagen Document adopted in 1990 by the Organization for Security and Co-operation in Europe (OSCE) and the relevant texts of the Council of Europe, in particular the Framework Convention for the Protection of National Minorities, the European Charter for Minority or Regional Languages and Assembly Recommendations 1134 (1990), 1201 (1993), 1255 (1995), 1492 (2001) and 1623 (2003) and Resolution 1713 (2010). It could guarantee the following minimum standards for national minorities and their members:

      6.1.       the right of every person to express freely his or her belonging to a national minority;

6.2.       political rights (such as freedom of association, the creation of political parties, participation in elections, representation in public bodies, at both national and regional level);
6.3.       cultural rights, including the right to cultural autonomy to preserve national identity;
6.4.       the right to take decisions on different forms of autonomy, in accordance with European practice and national or regional traditions;
6.5.       the right to freely use a minority language in private and public life, especially in relations with the administrative authorities or the judicial system in areas where national minorities reside traditionally or represent a significant percentage of the regional or local population.

I'd say that organise support for the protocol is a good starting point as it allows debate and will give the opportunity to tour the opponent's arguments.
