This question asks for your personal experience, so it's best you tell your personal story. But i can give you some ideas:
You might have witnessed some minorities being discriminated, for example religious, sexual or ethnic minority.
Maybe you commented then that you know someone of this group and that they're ok - that would be a good example! Then maybe you saw the other person challenge or change their views. If this ever happened to you, you can just describe it in detail!
Donne used the metaphysical conceit in the poem in Holy Sonnet XIV by having a strict form of the sonnet which helped the readers understands the themes implied by the poem. An iambic pentameter was also used in the poem.
I hope my answer has come to your help. God bless and have a nice day ahead!
