I understand that your heart is in the right place, but this is woefully naive.
Convincing someone right wing to come to the left is to convince the right wing that the majority of profit should benefit labor. If the right believed that they deserved the products of their labor, they would be left.
Shaking hands with racists, sexists, homophobes, bigots, transphobes, etc. Is regressive and puts minority groups in danger.
The right does not see that they are victims of Capitalists. The left, does. Thus, the left need to bring the right to the left.
