I subscribe wholeheartedly to this point of view
It is always better to be specific when indicating your point of view in a measured response opinion. Since you continuously represented the 2 opposing opinions in a single sentence, your response should clearly indicate the opinion that you support. For the sake of opinion clarity and proper thesis statement presentation. By the way, you are missing a clear thesis presentation. There is no summary of the reasons you will be discussing in the reasoning and supporting paragraphs. You need to mention 2 related ones to achieve that requirement.
Use uniform numerical ordinals. First, second, third. Do not mix first, secondly, third, fourthly... That is incorrect grammar.
The conclusion needs to follow the correct format. At least 2-5 sentences composed of individual discussion ideas. Do not compress the information in a single sentence since you are expected to follow the paraphrase + writer's opinion format from the first paragraph. That is called the reverse paraphrase.
