3 adjectives to describe vindicators

We had with us to-day at dinner, at my house, the Lady Dowager Colvill, and Lady Anne Erskine, sisters of the Earl of Kelly[1052]; the Honourable Archibald Erskine, who has now succeeded to that title; Lord Elibank; the Reverend Dr. Blair; Mr. Tytler, the acute vindicator of Mary Queen of Scots[1053], and some other friends[1054].

This claim, wild as it may seem; this claim, which supposes dominion without authority, and subjects without subordination, has found among the libertines of policy, many clamorous and hardy vindicators.
