You will hardly have any doubt as to who will receive the benefit of the poison.

Estranha gente, para quem é fora de dúvida que ninguém pode ser moral sem ler a Bíblia, ser forte sem jogar o críquete e ser gentleman sem ser inglês! E é isto que os torna detestados. Nunca se fundem, nunca se desinglesam.

Только полный идиот может думать, что крупный канал готов работать ради информирования зрителя. Канал продает продукт, его надо паковать. CNN, к примеру, является на Западе колоссальным идеологическим инструментом. Яркий пример тому - ситуация вокруг Югославии. Как эффектно промыли мозги очень цивилизованной части человечества! Вопрос в методах. Если потребитель "хавает" черствый хлеб, никто не будет давать ему булочки с маком. Я человек ангажированный абсолютно. Самим собой. У меня есть конкретные политические взгляды. Я не журналист. Я занимаюсь политической пропагандой. Я комментатор, и если человек комментирует события, не имея своей позиции, то это явление болезненное.
