Any moral theory can be interpreted as 'forcing' you to do altruistic acts as far as it can be said to show you why you should always act with the good in mind, where what is good is determined by that specific theory - and therefore to always put the good above self-interest.
So if you are a Kantian idealist, you may say that your rationality 'forces' you not only to act altruistically but also to enforce altruistic behaviour upon others. But that is no more than to say: enforce the categorical imperatives without letting your interests be a factor in your decision.
Similarly, if you are a consequentialist, you may say that consequentialism forces you to be altruisitic by forcing you to renounce self-interest when the consequences so dictate.
But all these are no more than just 'notational' variations. I believe the question is not a valid question. I will explain why. As I see it you are asking the following question:
Which theory of moral philosophy forces others (sometimes by coercion) to act altruisitically?
Now a 'theory of moral philosophy' could, by definition, be taken as a certain set of beliefs that promulgates a certain 'conception of the good'. Altruism is, by definition, a type of selfless behaviour that aims to promote the good of others. With these definitions in mind we can rephrase the question as follows:
Which conception of the good forces others to behave in such a way that their sole concern is the good of others?
And the answer to that question is: Those conceptions of the good that make such behaviour good. Which is to say: Those conceptions that make it good to determine behaviour according to the good of others. But here you can see that we have reached an impredicative definition: the 'good' is part of both the definiens and the definiendum. So no such moral theory can be provided wherein the forcing of good is considered good - without, that is, lapsing into incoherence.
I think your question looks like a valid question - but take care to unpack the definitions and you will see that it makes no sense to argue or demand such a position without becoming incoherent. Which, I guess, is confirmation that this idea comes from the mainstream media.
