You may be referring to laws such as the public order act in the UK and that is not dedicated to protecting Islam.
Section 5 of the Public Order Act 1986
A section 5 offence comprises two elements:
A person must (a) use threatening, abusive or insulting words or behaviour, or disorderly behaviour, or (b) display any writing, sign or other visible representation which is threatening, abusive or insulting; and
The words or behaviour, or writing, sign of other visible representation must be within the hearing or sight of a person likely to be caused harassment, alarm or distress thereby.
Section 5 Of The Public Order Act 1986: The Impact Of Harvey v DPP - Criminal Law - UK
Parts 3 and 3A- Racial and religious hatred[edit]
If the act is intended to stir up racial hatred Part 3 of the Act creates offences of
use of words or behaviour or display of written material (section 18),
publishing or distributing written material (section 19),
public performance of a play (section 20),
distributing, showing or playing a recording (section 21),
broadcasting (section 22). or
possession of racially inflammatory material (section 23)
Acts intended to stir up religious hatred are proscribed in POA Part 3A by the Racial and Religious Hatred Act 2006 (RRHA) with the insertion of new sections 29A to 29N.[3] The RRHA bill, which was introduced by Home Secretary David Blunkett, was amended several times in the House of Lords and ultimately the Blair government was forced to accept the substitute words.
To stir uphatred on the grounds of sexual orientation was to be proscribed by the Criminal Justice and Immigration Act 2008 in POA Part 3A section 29AB.[4] This legislation was introduced by David Hanson MP.

If you can provide a link to any European law on the statute books which makes it a crime to insult Islam then please post it. Or is this yet more "information" from one of your
racist sites?
