I'm one of 'em!
(But I believe you mean "textual critics" rather than "translators".) And of course "minority" certainly does not mean "wrong," as you know.

These are unproven assertions. There are mss from the 2nd century with various readings, even Byzantine. But Sinaiticus and Vaticanus, used most often to prove Alexandrian priority, are 4th century.
But even if the Alexandrian is from the 2nd century, so is the Old Syriac. "In general, the Old Syriac versiojn is a representative of the Western type of text" (
The Text of the NT, Metzger and Ehrman--ugh--p. 97) but nobody today considers the Western to be the original. So having early mss does not prove that a reading or text is the original.
"A popular misconception is that the earlier the witness, the earlier and more authoritative the text presented by that witness, merely because such a witness is chronologically closer to the time of autograph composition. It is known, however, that virtually all sensible variant readings came into existence in the tumultuous second century...,and that what is reflected in all our extant manuscripts is a mixture of variant readings that date back into the obscurity of that era from which we have but scant textual information" (Maurice Robinson
, "The Case for Byzantine Priority," in
Rethinking NT
Textual Criticism, ed. by David Alan Black, 2002, p. 135).
Very true.
