I'm watching a video about Passive Causative;as of the minute 2:07 there is a sentence written on the board that it's read as:
I am made to shut up
Given that he is using the present form of the verb to be, should no be using make instead of made?
Also I found that the construction of make as a causative is
[make + person + verb]
and in this construction I don't see the "person".
So my question is Is am correct or must be was and why?
Given that he is using the present form of the verb to be, should no be using make instead of made?
No: made is correct. The passive voice is constructed from be plus the past participle. (In the case of to make, the form made serves as both past participle and past tense — and this is true of most English verbs — but you can see the difference with a verb like to see: we say "I am seen", not *"I am see" or *"I am saw".)
[…] and in this construction I don't see the "person".
The "person" is the object of make. Your example uses the passive voice, so the object is converted to a subject (namely "I"). "I am made to shut up" means "[Someone] makes me shut up."
The whole construction isn't brilliant. "Make somebody do something" is confortable in use "as is", when you start switching tenses, you may make a complete mess of it. As of some proposition instead, use "he was forced to shut up" or "they made him shut up", that will make your language rich and inventish.
