It might have been the Irish, but not the poles.
Without comment, they should be asked a series of yes or no questions first:
1. Is abortion a state or federal government issue?
2. In your opinion as a human being, husband and father, should abortions be allowed up to birth of child?
3. Are there just two sexes, male and female?
4. Is there biological differences in male and female?
5. Should biological males be allowed to participate in female sports?
6. Are the differences permanently physical?
7. Should immigrants be allowed in our country without being vetted?
8. Should someone entering the country illegally be arrested and deported?
9. Should we complete the border wall?
10. Should all energy sources at our disposal be used to bring costs down for US citizens?
11. Should energy changes be allowed to happen naturally instead of forced by the Fed?
12. Should any elected official be allowed to profit from his or her position beyond the salary and benefits provided by the government?
13. Should taxes be lowered for every citizen?
Then you can allow them discussion, but cannot speak about their opponent, only about themselves and what they do.
