....this sentence soudsvery confusing. You should introduce your prompt
In a more simple, yet interesting way. Do not crowd your sentences unnecessarily. Tell your ideas in a more direct and simple manner and let them flow logically.
I suggest you to follow this structure:

Body para 1: State the 1st reason for your opinion. Provide an example to support thatreason
Body para 2: 2nd reason + example
Conclusion : yur final statement about your position
