People do not know what fallacies are

It depends on your definition of people. Are these "people" the general public? By "people" do you mean people who do not know what fallacies are? This claim could be argued either way depending on that definition.

Marriage is a highly sentimental institution that is hardly worth arguing over. Resolving this debate should be very easy, as it is simply frivolous and unnecessary to human life. If you care so much about marriage on either side of the debate, your priorities suck.

Irrelevant Conclusion

We can know nothing for certain

You cannot know, because knowledge is based on facts, and facts assume there is an "absolute truth". There is no absolute authority on truth. We only have each others subjective experiences to compare. You can be certain of anything, but you cannot "know" anything for certain.

"Reasonable" is a subjective term. Who is to decide what doubt is "reasonable"?
