Teacher Luis María Llena León publishes regularly on his personal blog No hay mejor maestra que la vida  (There is no better teacher than life; es), and wrote recently his opinion  about the sensitive issue of tolerance, noting that “to respect every opinion is a fallacy”, as it has been in favor of world tolerance. Instead, the author thinks that, although every individual deserves to be respected, there are opinions that can't be respected and they must be fought, refering to the xenophobic ideas by Jean Marie Le Pen.
La dignidad de todo ser humano (que posee por el hecho de ser humano) merece nuestro respeto; pero hay acciones e ideas que no lo merecen.
The dignity every human being has (due to the fact of being human) deserves our respect; but there are actions and ideas that don't deserve.
