Guilt and shame are stone age tools to get people to be obedient and fit into domination based hierarchies. Lot of cavemen still use them. But this is not the stone age and there are better ways of getting things done. The Outcomes speak for themselves when you use guilt/shame/fear/duty/obligation and when you dont.

Marshall Rosenberg on the subject - "We all pay dearly when people respond to our values and needs, not out of their own desire, but out of fear, guilt, or shame. Sooner or later, we will experience the consequences of diminished goodwill on the part of those who comply with our values out of a sense of either external or internal coercion. They, too, pay emotionally, for they are likely to feel resentment and decreased self-esteem when they respond to us out of fear, guilt, or shame. Furthermore, each time others associate us in their minds with any of those feelings, we decrease the likelihood of their responding compassionately to our needs and values in the future."

The more productive way to do things is to just focus the conversation on your needs and values. And leave it at that. Don't bring judgement/blame/demands/guilt/shaming etc into the picture and then watch the difference in how people respond to your political positions.
