Marco, I really don't think it's helpful throwing around accusations such as discriminatory/racist, which unfortunately are terms that have rather lost their potency recently as they have been applied far too indiscriminately. I realise younger people tend to accuse rapidly things they strongly don't agree with as 'Nazi' or 'Hitler', but we're surely more sophisticated than that. If you don't agree with something fine, but such emotive language doesn't help.

I struggled to understand your point by point disagreement with the manifesto, which seemed to range from strongly eschewing all suggestions of societal/cultural agreed authority, and degrees of conformity, but then you alluding to the Bible on one point which surely itself is rather (in some readings) a very authoritative text (not that I believe that is necessarily a 'bad thing').

Your use of the Welsh speaking population of Wales as an example, is rather lost on me, but perhaps indicates some mutual misunderstanding that has caused you to take offences when none is being given?

We're talking about shared values, which evolve biologically, over time, in all cultures - where there are new communities joining. For example, we (currently) have monogamy in marriage in this country, we don't see polygamy as lawful. Many cultures take different views, but while the law prohibits this (authority exercised) then most people in Britain comply. Same with age of marriage, same with FGM, etc. All authoritatively upheld in the UK, where the Law and the Police are the authority (see relevant point in the manifesto you disagreed with), not minority community leaders, or individuals themselves. None of that is racist/discriminatory? It's what the majority of people in the country believe to be right, at the moment. It may change - just like same-sex marriages are now legal (which of course some minority groups in the UK are appalled by - but that's not racist or discriminatory either to allow such marriages).

No one is claiming that having different languages spoken in a community is a problematic issue (far from it - it's an enrichment), but where a minority language is your only language, and if this actually reinforces isolation for some parts of the wider countries community, into ghettos, or silos of culture, rather than allowing an active participation by ALL groups to contribute to a country's culture, that can surely be problematic and lead to friction. That is, if you can't actively take part in a community because you can't effectively communicate, it must be very difficult to feel welcomed and aligned with, and contribute to, that wider community. Coming to live permanently in a new country, it is a commonly held courtesy to attempt to learn that country's primary language(s). Granted, the stereotype is that some Brits aren't necessarily very good at that when living abroad - but that's another issue.
