I think you might be playing semantics here.
Discrimination is defined as;
'
treating a
person or
particular group of
people differently,
especially in a
worse way from the way in which you
treat other
people, because of
their skin colour,
sex,
sexuality, etc.:' 1

discrimination
Refusing people a blessing would certainly be treating them differently than others due to sexual preference.
I think what you are trying to say here is that it is ok to discriminate against them because of the beliefs motivating the discrimination, or because you think God is behind the discrimination (albeit without evidence)
This "blessing" of the Catholic Church does not affect a marriage contract at all.
It is simply the means by which they express their consideration of whether a marriage is valid or not -
according to the Church.
You and I and no one else has any business telling any Church how it should run itself or what it should believe.
As long as the Catholic Church is not violating any law - they are free to practice their beliefs as they see fit.
Also - you are acting as if same-sex unions are the only marriages the Catholic Church has ever chosen not to bless.
The Catholic Church is known for not blessing marriages if the Catholic spouse marries a non-Catholic, if a Catholic decides to get married somewhere other than at their own parish, if the participants have been divorced and a plethora of other reasons.
Were these refusals "especially" more discriminating? Was this discrimination "worse" somehow?
The fact of the matter is - the Catholic Church has their own standards and beliefs and they operate according to them.
Everyone and their grandma knows the Catholic Church's stance on homosexual behavior and marriage.
If people act contrary to these things - the Catholic Church can refuse to extend particular benefits of membership in their Church - such as a blessing - to those people.
They are well within their rights and there is nothing
immoral about it.
Granted - they have no evidence that any of these beliefs come from God - it is just their opinion - but you also have no evidence that the Catholic Church's refusal to bless same-sex unions is
immoral - that is simply your own opinion.
What's next? Are you going to claim that they need to baptize everyone or else they are discriminating?
Well I can't speak for everyone, but I don't know of the German priests trying to "force" the Catholic Church to bless their unions.
Of course they are. Why else would they do it? What's the point in protesting if you aren't demanding any change?
What I assume they are doing by livestreaming their blessings is publicly protesting the church's attempt to coerce (ie force) them into not blessing same sex unions of gay couples through threat of excommunication and the like.
Yet - all of their "authority" to bless any union comes from the Vatican.
This is like saying a group of police officers began livestreaming themselves breaking the law to protest the State's attempt to coerce (i.e. "force") them into enforcing the law by threat of termination of employment.
Sure - both the police officers and these German priests are free to protest whatever they want - but they shouldn't expect to keep their jobs - because they aren't doing their jobs - and they are abusing the authority given to them by using it for their own selfish aims.
