Re Norwood vs UK:

> Norwood, a member of an extreme right-wing political party [the British National Party], placed a poster on his apartment window that called for the removal of all Muslims from Britain.

> the poster in question contained a photograph of the Twin Towers in flame, the words “Islam out of Britain – Protect the British People” and a symbol of a crescent and star in a prohibition sign. The assessment made by the domestic courts was that the words and the images amounted to an attack on all Muslims in the UK. The ECtHR largely agreed with the assessment, and stated that such a general, vehement attack against a religious group, implying the group as a whole was guilty of a grave act of terrorism, is incompatible with the values proclaimed and guaranteed by the Convention, notably tolerance, social peace and non-discrimination

Re Melia:

> Melia was the head of the Telegram Messenger group Hundred Handers, a social media channel that generated racist and anti-immigration stickers that were printed off and displayed in public places.

> The stickers contained "ethnic slurs" about minority communities which displayed a "deep-seated antipathy to those groups", the court heard.

> The judge told Melia: "I am quite sure that your mindset is that of a racist and a white supremacist.

> "You hold Nazi sympathies and you are an antisemite."

> Melia, who was also found guilty of encouraging racially-aggravated criminal damage, was sentenced to two years for each charge to run concurrently.

Interesting that the cases that spring to mind for you are literal neo-Nazis.
