There are anti-semetics hiding behind the 'free speech' banner, saying they have a right to try and convert more people to anti-semetism, and that nothing should stand in their way. It's not the other way around.
The version of Article 19 in the ICCPR amends the "freedom of expression" by stating that the exercise of these rights carries "special duties and responsibilities" and may "therefore be subject to certain restrictions" when necessary "[f]or respect of the rights or reputation of others" or "[f]or the protection of national security or of public order (order public), or of public health or morals".
