Why should someone who is Scottish from Scotland have a say in it at all as it is NONE of their business, NONE.
Sorry, but as a Polish citizen, I have the right to vote on such matters. Jon too, for that matter. Both of us vote for parties that maintain the status quo, that is, keeping Polish citizenship out of the hands of people with no clear connection to Poland.
Someone with ancestry certainly has priority over an ex-pat through marriage riding the shirttail of a Polish person.
No such thing as "priority", nor is there any special treatment for obtaining Polish citizenship through marriage. Your ignorance about Poland is outstanding.
