Opponents of gay marriage have staged a demonstration outside a meeting of the Scottish cabinet.
The group Scotland For Marriage staged the protest before the meeting at Renfrew Town Hall.
...Scotland For Marriage, which is backed by the Catholic Bishops' Conference of Scotland and the non-denominational Christian Institute charity among others, has described the proposals as "ill-conceived and poorly thought-out".
The campaign group will use the protest to raise fears that changing the law could see teachers disciplined if they refuse to use books about same-sex relationships.
A Scotland For Marriage spokesman said: "Parents may also find it difficult to withdraw children from classes.
..."Our supporters are highly motivated and harbour deep fears for the future that if the marriage laws are redefined, gay marriage will be promoted to schoolchildren in Scotland."
