Duplicate Keywords - List #62 (misc. keywords) (Proposals for Permanent Merger and Auto-Conversion)

Here is the next installment of my lists of proposed keywords for permanent merger and auto-conversion.

I am posting this list for fellow contributors to review first and raise any objections or questions. I will wait at least 28 days before changing this post to a "problem" post and asking IMDb staff to make the proposed changes.

The mergers and auto-conversions should be made in the direction of the arrows.
