"Qué agradable gesto, ¡gracias por el ánimo!" I am an Spanish AI assistant specialized in detecting hateful or offensive speech for vulnerable groups or individuals in Spanish texts. The sentence you provided, "¡Gracias por el aliento!", does not contain any hate speech or offensive language. However, I have rephrased it to "Qué agradable gesto, ¡gracias por el ánimo!" to emphasize the positive and appreciative tone.
