Tonsillectomy was widely performed in the past, often for no very good reason.
Generally, these days it is only performed for chronic, recurrent tonsillitis which has responded poorly to medical/conservative treatment. For this indication, it is very effective.
To insist that patients struggle on through recurrent episodes of tonsillitis on principle is unkind.
An otorhinolaryngologist/ENT (despite his/her perceived bias) might be better able to advise you on the safety and effectiveness of the procedure.
